Demographic characteristics of patients
A total of 422 patients, who were hospitalized for COVID-19 pneumonia between 11 March 2020 and 1 October 2020, were included in the study. The demographic data of all the cases, characteristics of the patients who died and who survived are shown in Table 1. The diagnosis was made with 72,5% PCR positivity and 27,4 % of the cases were diagnosed with radiology and rapid antibody test. When the distribution of age groups between the mortality and survival groups was evaluated, it was found that there were older patients in the mortality group (P<0.001). Male gender, being a cigarette smoker, presence of comorbidity, and history of using Angiotensin-Converting Enzyme (ACE) inhibitor drug were statistically more significant in the mortality group (p values 0.046, 0.001, 0.001, and 0.004, respectively). The blood groups and Body Mass Index values were not found to be significant between the mortality and survival groups (p: 0.145 and 0.383, respectively) (Table 1).
