Number of patients operated on for oncological and non-oncological conditions as a function of time and phases of the COVID-19 Pandemic. Horizontal dashed lines demarcate the pandemic phases– I (first wave), II (second wave– period of a significant reduction in surgical movement), and III (post-pandemic recovery). The solid lines (red) and dashed lines (green) are the results predicted by the Newey-West model used in the analysis of interrupted time series
