Effect of Low-Fat Diet vs. High-Fat Diet on Serum Adiponectin Levels Forest plot displaying the Weighted Mean Difference (WMD) and 95% confidence intervals (CIs) for the effect of a low-fat diet compared to a high-fat diet on serum adiponectin levels (measured in ng/mL). Each study is represented by a square, with its size proportional to its weight in the meta-analysis. The diamond represents the pooled effect estimate, with its width indicating the confidence interval. A positive WMD favors the low-fat diet, suggesting an increase in adiponectin levels
