Fig. 3. Studies evaluating 20-item Toronto Alexithymia Scale (TAS-20) scores in irritable bowel syndrome (IBS) patients vs inflammatory bowel disease (IBD) patients. The figure shows an overall mean difference between the TAS-20 scores in IBS patients vs IBD patients of 0.884 (95% CI, –2.536-4.304). Hence, TAS-20 scores are not significantly different between both groups. The heterogeneity is not significant with an I2 of 26.89% and a P-value of 0.242.
