Fig. 2From: Early postoperative changes of sphingomyelins and ceramides after laparoscopic sleeve gastrectomySerum ceramide levels. Values measured in control group (n = 15) and LSG patients (n = 20). All values are mean ± SEM. a C16 Ceramide (d18:1/16:0) b C18 Ceramide (d18:1/18:0) (c) C20 Ceramide (d18:1/20:0) d C22 Ceramide (d18:1/22:0).*, p = 0,014 vs. sleeve gastrectomy preop. Statistical analysis was done by paired t-test. #, p = 0,008 vs. control Po Day 1. Statistical analysis was done by t-test. **, p < 0,001 vs. sleeve gastrectomy preop. Statistical analysis was done by paired t-test. ##, p < 0,001 vs. control Po Day 30.
