Statistical analysis
Statistical analysis was performed using SPSS ver. 23.0 (SPSS Inc., Chicago, IL, USA). P -value of < 0.05 was chosen for statistical significance. Baseline clinical data of the patients and blood indices were expressed as mean ± standard deviation for continuous variables or as numbers with percentages for categorical data. Studentt test was used to identify differences between complete recovery and partial recovery groups for continuous variables. The chi-square test was used for comparisons of categorical variables. Multivariate logistic regression analyses were used to calculate the odds ratio and confidence intervals [OR (CI)] and assess the association of complete blood count indices and baseline characteristics with post-acute COVID-19 recovery status.
