Figure 4. Pooled estimates of incisional hernia comparing continuous nonabsorbable versus continuous absorbable closure. Squares indicate point estimates of odds ratios, with the size of the square representing the weight of each study. Horizontal bars signify 95% confidence intervals. The summary odds ratio is represented by the diamond; values to the left of the vertical bar favor the continuous nonabsorbable group and values to the right favor continuous absorbable.
