Demographics and cyst characteristics after exclusion of patients with cysts <0.5 cm and >75 years old are presented in Supplementary Material Table S2.
Continuous data are presented as means (standard deviation) and categorical as absolute values (percentages) with P-values resulting from analysis using chi-squared for categorical data and ANOVA for continuous data.
