Methods
Out of patients diagnosed with Covid-19 admitted to Health Sciences University Diyarbakır Gazi Yaşargil Training and Research Hospital and Ayancık State Hospital from April 1, 2020, to April 1, 2021, 424 patients were randomly and retrospectively included in the study. All patients included in the study were Covid 19 positive according to the World Health Organization (WHO) guidelines. Demographic and clinical characteristics such as age, gender, and length of hospitalization were obtained from the digital records of participants. Biochemical, hormonal, and hematological parameters of these patients were analyzed retrospectively.
Patients with previous diagnoses of cancer, endocrine disorders, liver or kidney failure, autoimmune diseases, infectious diseases, and under 18 were excluded from the study. Due to the retrospective and anonymous nature of the study, written consent from the participants was waived. Participants were divided into living and deceased groups. All patients were followed up daily until discharge or death. All study procedures were according to the principles of the 1964 Helsinki Declaration and the subsequent 2013 amendment.
Mann-Whitney U test was used to compare quantitative data between living and deceased groups. The chi-square test was used to compare death rates according to gender. Binary logistic regression analysis was used to determine the risk factors affecting death. Data were analyzed using IBM SPSS V23 (IBM SPSS Statistics for Windows, Version 23.0. Armonk, NY: IBM Corp). The significance level was taken as p <0.05.
