“…There were insufficient data to pool outcomes of individual treatments (except for POEM), so we pooled data into two categories: medical or endoscopic. Medical treatment (pooling data on calcium channel blockers, nitrates, PPIs, peppermint oil, and antidepressants) resulted in a pooled clinical success rate of 62.6% [95% CI: 46.5%‐78.7%; Cochran's Q = 9.2, I 2 = 45.8%] 20,21,23,25,31,52 . Endoscopic treatment (pooling data on endoscopic dilation, endoscopic Botox injection, and POEM) resulted in a pooled clinical success rate of 79.4% [95% CI: 74.2%‐84.5%; Cochran's Q = 2.8, I 2 = 0%] 21,23,25,31,49‐51,53 and this was significantly superior to medical treatment ( P = .012) (Figure 5).…”
