3.1. Baseline patients’ characteristics
The number of patients analyzed during Delta predominance was 1170, of whom 490 received RDV treatment. During the Omicron surge, the number of patients enrolled in the study was 652, of whom 272 were treated with RDV. In both periods, a slight male predominance was observed. During the Omicron-dominated period, patients treated with RDV had significantly lower BMI and higher age than the corresponding group during the Delta wave (Table 1).
