Figure 9
Forest plot illustrating changes in albumin levels over time. This plot indicates a significant difference in albumin levels between groups across various studies over time, with each subsequent study reinforcing the observed trend (P < 0.001). The gray squares represent the effect estimates of individual studies, with the size corresponding to the weight of the study in the meta-analysis. The horizontal lines through the squares indicate the 95% confidence intervals. The gray diamond represents the pooled effect estimate across all studies. SMD stands for standardized mean difference.
