Data are presented as mean ± standard deviation. Between-group comparisons were done with independent samples’ t-test, and within-group comparisons before and after the operation were done using paired t-test. RYGB: Roux-en-Y gastric bypass; OAGB: one-anastomosis gastric bypass; preOP: prior to the operation; postop: after the operation; BG: blood glucose; CV: coefficient of variation. The times spent in each of the glucose ranges are given as percentages of time relative to the total wear-time of the continuous glucose monitor.
