Allium sativum-LDL	WMD = -4.99 (-5.4 to -4.59); 20^ab; I² = 65.7%	WMD = -5.05 (-5.45 to -4.64); 13^ab; I² = 96.4%
Allium sativum-HDL	WMD = 1.15 (1.05 to 1.25); 21^ab; I² = 77.7%	WMD = 1.15 (1.05 to 1.25); 11^ab; I² = 86.4%

^a P < 0.001 for the main effect.
^b P < 0.001 for Cochran's Q test.
HAM-D = Hamilton Depression Scale score; HDL = high-density lipoprotein; LDL = low-density lipoprotein; TC = total cholesterol; TG = triglyceride; WMD = weighted mean differences.
