Effect of Different Membranes on Vertical Bone Regeneration: A Systematic Review and Network Meta-Analysis

Figure 4

A forest map of pairwise comparison. A forest plot of pairwise comparison. The black horizontal lines represent the confidence interval (CI) of each study. The black solid diamonds represent the standard mean difference (SMD) for each study. The blue hollow diamond represents the result of pairwise comparison or the result of the entire study. The gray squares represent the weight of individual studies; therefore, the larger the sample size, the larger the weight and the larger the square area. The black vertical line in the middle is an invalid line.
