Figure 2: Forest plot of the metaanalysis for the association between exercise and HDLC when random affects model were used. The size of the blank boxes for each outcome represents the weight given to that outcome. The overall mean difference was shown by the middle of the diamond while the left and right extremes of the diamond represent the corresponding 95% CI. The vertical red line represents the overall mean. Net change in HDLC was calculated as the difference (exercise minus control) of changes (final minus initial) in the mean values from each study. HDLC = Highdensity lipoprotein cholesterol, CI = Confidence interval
