Notable findings included body fat with (Cochran’s Q = 48.7; Pheterogeneity = 3 × 10–3), Type II diabetes (Q = 119; Pheterogeneity = 7.40 × 10–14), Fasting insulin (Q = 35.75; Pheterogeneity = 9.30 × 10–5), C-reactive protein levels (Q = 34.48; Pheterogeneity = 3.00 × 10–3), Leptin (Q = 42.36; Pheterogeneity = 5.70 × 10–5), Triglycerides (Q = 268.09; Pheterogeneity = 2.35 × 10–19) and HDL Cholesterol (Q = 250.2; Pheterogeneity = 1.52 × 10–10).
