Dear Editor in Chief,
Recently, using statistical tests as useful and ubiquitous tools in medical data analysis is increasing (1). However, some researchers are using statistical methods without sufficient knowledge. The purpose of this letter is to provide applied information on some of the most commonly used statistical tests.
All statistical tests examine a hypothesis. A hypothesis is defined as a claim that its accuracy or inaccuracy is unknown (2). In general, variables are divided into quantitative and qualitative categories (3). Some popular statistical tests that examine the relationship between two or more variables are summarized bellow according to the main purpose of this article.

Dear Editor in Chief
During the disease epidemic in Iran, the government first considered emergency measures for the center of the disease epidemic, the Qom province, and after that by observing new cases in Tehran, Gilan, and Mazandaran provinces, which are the adjacent provinces to Qom province, the emergency measures for these three provinces were considered as well (1).

Dear Editor in Chief
Reliability and validity are concepts used to evaluate the quality of psychometric properties of a scale in medical research. Reliability is related to reproducibility, and validity is related to the accuracy of a scale. It is important to check reliability and validity when using a scale or questionnaire. The present study provides a brief overview of the types of validity and reliability in medical research.

Abstract
Introduction: . Yazd province is the center of Iran and the highway for travelers to other cities. This province is susceptible to disease transmission in Iran. this study aimed to spatial analysis of corona virus prevalence, predicting the spread and determination of hot spot areas in Yazd province, central part of Iran.
Methods: This analytical Cross-sectional study was conducted in Yazd province from February 2020 to January 2021. Patients with COVID-19 admitted to hospitals in Yazd province were selected by census. Required information includes the number of patients as well as their place of residence were collected through the hospital information system (HIS) of Shahid Sadoughi Hospital in Yazd, Iran. The inclusion criteria were positive polymerase chain reaction (PCR) test for COVID-19 and registration of patient information in the hospital emergency department. After collecting the data, it was entered into the ArcGIS software is 9.3.1. software. Moran's I measure and chi square test were used to data analysis. Significant level were considered 5 %.
Results: Overall disease prevalence in Yazd province was equal to 0.0053. The prevalence of disease was higher in men (55.7% , 3412 cases). The highest prevalence of the disease occurred in Yazd city (0.0096) and the highest death occurred in Meybod city (20.8%). Bahabad city also had the highest number of transfer (2.7%). Areas one (15.2% and 932 patients) and two (15.9% and 975 patients) of Yazd city were the most infected areas. There was no significant spatial pattern between the prevalence of the disease in the cities (Moran's Index: 0.18, P-value = 0.58).
Conclusion: There was no spatial pattern in the prevalence of the disease and only in the city of Yazd, regions one and two need the special attention of policymakers.

Abstract:
Introduction: Influenza virus is one of the deadliest viruses that has threatened the human population over the years. Every year, organizations and hospitals must be prepared to deal with the disease and treat people with the flu and be able to manage the disease in the hospital. The aim of this study was to identify hospital management strategies for human influenza in Yazd province, central part of Iran.
Methods: This study was a qualitative study with inductive conventional approach. A total of 14 main hospitals in Yazd province were surveyed in 2021. The study population included heads and managers of hospitals, nurses, educational and clinical supervisors, metrons, officials of the quality improvement office and the infection Control Committee. Participants were selected using snowball sampling method. semi structured interviews were used to collect data. The sample size in this study was up to information saturation. Content analysis method was used to analyze the data.
Results: Using the opinions and views of 38 managers and officials of selected hospitals in Yazd province, data saturation was obtained. The most important tasks of the hospital management in terms of influenza control and management were divided into 5 areas (field measures, support, training, awareness, protection and measures in the field of human resources). The major challenges regarding the influenza control and management were classified into 3 areas: hospital (health), macro (university, provincial, national and Ministry of Health guidelines) and community level. Finally, the most important solutions and suggestions were categorized in these 3 key areas.
Conclusion: Based on the categorized challenges and problems, as well as the classification of the most important strategies and suggestions, useful action can be taken to the control and management of influenza, both at the hospital level and in the community, in Iranian hospitals especially in Yazd province.

Abstract
Introduction: The World Health Organization on March 11, 2020 declared the outbreak of severe acute respiratory syndrome Corona virus 2 disease (COVID-19) a pandemic situation. The main aim of this study was investigating mortality of COVID 19 by considering chronic diseases.
Materials and methods: this study was conducted as a cross-sectional in which all confirmed cases were examined. The variables considered in this study were age, sex, diabetes mellitus, cancers, hypertension, heart diseases, kidney diseases, and liver diseases. Independent sample t test, Chi-square and binary logistic regression were used to data analysis. All statistical analysis was done in SPSS 16 and significant level was set at 0.05.
Results: Out of 22849 PCR and CT scan tests, 16061 ones were positive. According to the confirmed cases, prevalence of COVID-19 was calculated about 0.019. Also hospital case fatality rate and mortality rate were calculated 156 and about 8.2 per 100000 respectively.
Hypertension, and age had significant relationship with morbidity of COVID-19, in other hand, age (OR: 4.51, p<0.001), kidney diseases (OR: 1.84, p<0.001), diabetes mellitus (OR: 1.31, p<0.001), cancer (OR: 2.73, p<0.001), liver diseases (OR: 2.27, p<0.001) had impact on mortality of covid-19. Population Attributable Fraction (PAF) showed that diabetes mellitus, cancers, kidney diseases, and liver diseases had 4.2, 2.4, 1.3, and 0.2 percent, respectively.
Conclusion: age and some underlying diseases increase odds of death due to COVID-19. It seems that preventing high-risk people from being infected is an effective solution to reduce COVID-19 death rate. To do this, health protocols need to be implemented more seriously for these sensitive groups.

Abstract
Introduction: One of the main pillars of the study is the correct choice of study design. This study aimed to give an overview of different type of study designs in medical research.
Methods: In this tutorial study, all applied research designs in terms of quantitative and qualitative study were reviewed. Accordingly, terms related to "Research Designs" were searched in the online databases such as Google Scholar, PubMed, Web of Science and Scopus.
Results: Based on the findings of the present study, the types of studies are generally divided into two groups: quantitative studies and qualitative studies. Quantitative studies are divided into two categories: primary and secondary studies. Preliminary studies include observational and non-observational studies. Observational studies are divided into two categories: descriptive and analytical studies. Descriptive studies include case reports, cross-sectional studies, cross-sectional correlational studies and ecological studies, and analytical studies include retrospective and group studies. Non-observational studies also include laboratory studies, clinical trials, field trials, and community trials.
Conclusion: With a good understanding of the types of studies, it is easy to decide which type of study is appropriate for the research. Choosing proper study design can reduce the costs of the executive process, increase the accuracy, quality of research and give more reliable results.
