  1. aDistribution of patients with maximal %WL across postoperative timepoints was compared between procedures using a χ 2 test for trend—a higher proportion of RYGBP patients experienced maximal %WL at the 24-month appointment, with lower proportions than the SG group at the 6- and 9-month appointments (important differences in bold)
