Values are medians (IQRs) or means ± SDs for continuous variables or frequencies (%) for categorical variables. COVID-19, coronavirus disease 2019; 25(OH)D, 25-hydroxyvitamin D.
Continuous values were compared by Mann-Whitney U test or unpaired t test; categorical variables were compared by Pearson's chi-square test (with continuity correction) or Fisher's exact test.
Information on BMI was available for 45 cases in the discharged group and 4 in the death group.
Including hypertension, diabetes, cardiovascular disease, cerebrovascular disease, chronic lung diseases, chronic kidney disease, and tumors.
Serum 25(OH)D concentrations <30 nmol/L.
Serum 25(OH)D concentrations ≥30 nmol/L.
