Bariatric surgery improves lipoprotein profile in morbidly obese patients by reducing LDL cholesterol, apoB, and SAA/PON1 ratio, increasing HDL cholesterol, but has no effect on cholesterol efflux capacity Christian Abendstein Kjellmo, MD, Helen Karlsson, PhD, Torunn K.

Figure 1 Serum levels of (A) LDL cholesterol, (B) HDL cholesterol, (C) triglycerides (TGs), and (D) apoB at inclusion, after a lifestyle intervention (∼3 months) and 1 year after bariatric surgery in 34 morbidly obese patients, and at inclusion for controls. Values are mean with standard deviation. *P < .05, **P < .01, ***P < .001, ****P < .0001, ns, not statistically significant.
