Comparison of the complication incidence rates and complication-free patient percentages between the UVPR and PVPR periods in the group of 84 patients. Note: The incidence rate of complications (expressed as complications per person-year) and the percentage of patients without any complications during the UVPR (2017–2019) and PVPR (2020–2022) periods were based on a dynamic cohort of 84 patients observed across both treatment strategies. A 3-year observation period was assumed for each patient in both the UVPR and PVPR phases.
