Data are for all subjects who completed 2 and 10 years of the study and are independent of diagnosis and medications at or after baseline. The changes with in each treatment group are unadjusted, whereas the differences between the group in the changes have been adjusted for sex, age, body-mass index (MBI), and the baseline level of the respective variable. CI de-noted confidence interval, and HDL high-density lipoprotein.
For values with in each group, minus signs denote decreases; for differences between the groups, minus signs denote smaller reductions or (in the case of HDL cholesterol) lager increases in the surgical group than in the control group.
P values are for the comparison with the bending subgroup.
P<0.001.
