Mean difference: mean change within subjects from baseline (presurgery) to follow-up (12 months).
P value for baseline to 12 months of follow-up mean difference (two-tailed).
Continuous variables described as absolute means (SD). Mean difference reported with SE in parentheses.
BMI, body mass index; BP, blood pressure; DBP, diastolic blood pressure; HR, heart rate; NA, not applicable; RYGB, Roux-en-Y gastric bypass; SBP, systolic blood pressure; SG, sleeve gastrectomy.
