Figure 7
Cumulative meta-analysis forest plot depicting albumin level differences over time. This plot illustrates the significant changes in albumin levels as additional studies are included over time, each reinforcing the overall observed differences (P < 0.001). The standardized mean difference (SMD) was represented by gray squares, indicating the effect estimate of each study at the time of its publication. The pooled effect estimates across all studies are shown as a gray diamond. Fourteen studies were observed to be outliers (asterisks)26,27,32,34,35,36,38,39,43,47,52,58,60,61.
