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

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