The secondary outcome was death occurring during the 14 days after admission to the hospital. In adjusted models, missing values were handled by multiple imputation.
Statistical analyses were performed using SAS software version 9. A total of patients were included in this study. The median duration of symptoms at the time of admission to hospital was 7 days interquartile range: 4β Platelet count within admission was assessed in patients.
Patient's characteristics are described in Table I. The prevalence of thrombocytopenia upon admission was Results regarding the association of thrombocytopenia upon admission and outcomes are presented in Table II. The population of this study was older and more severely affected than the initial cohorts from China.
