Table 2.
Multiple comparisons in contrast analysis. Column 1: intergroup comparisons between HF/HF, CD/HF, HF/CD, and CD/CD groups DJOS versus SHAM. Column 2: intragroup comparisons between HF/HF, CD/HF, HF/CD, and CD/CD groups after DJOS surgery. Column 3: intragroup comparisons between HF/HF, CD/HF, HF/CD, and CD/CD groups after SHAM surgery.

Post hoc analysis, statistical significance was set at p < 0.05. FABP4: fatty acid-binding protein 4; CRP: C-reactive protein; DJOS: duodenal-jejunal omega switch surgery; HF: high-fat diet; CD: control diet; HF/HF, CD/HF, HF/CD, CD/CD: type of diet 8 weeks before/8 weeks after surgery.
