Forest plot of pooled estimated SMD using random effect model.

The size of the x-axis shows the SMD estimate of the studies. Hard line indicates no difference (SMD = 0). In the pooled point calculation, the dotted line represents the mean difference. The black dot in the middle of the gray box reflects the SMD estimate of each sample’s point and the line shows the 95% CI of the estimates. The gray boxes represent each study weight that contributes to the estimation of the pooled mean difference. I-squared illustrates the heterogeneity between the included studies.</p

Forest plot of population based sub-group analysis.

The x-axis scale displays the estimation of the SMD in MPV. The hard line shows no difference. The dotted line represents the mean difference in the pooled point estimate of each study. In the center of the gray box, the black dot reflects the SMD estimate of each article’s point estimate and the line shows the 95% CI of the estimates. I-squared indicates the heterogeneity across the included studies, p indicating for statistical significance of heterogeneity.</p

Forest plot of pooled estimated MPV in IBD patients using random effect model.

The size of the x-axis shows the estimate pooled MPV of the studies. In the pooled point calculation, the dotted line represents the MPV. The black dot in the middle of the gray box reflects the estimate pooled MPV of each studies point and the line shows the 95% CI of the estimates. The gray boxes represent each study weight that contributes to the estimation of the pooled MPV. I-squared illustrates the heterogeneity between the included studies.</p
