Prospective trials with different doses of prucalopride versus placebo were selected. The frequency of spontaneous bowel movements (SBMs) per week and the treatment-emergent adverse events (TEAEs), such as headache, arrhythmia, diarrhoea, dizziness, nausea and vomiting, were first synthesised in a meta-analysis. The probability of optimal dose of prucalopride was then ranked by random-effects within Bayesian analysis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>14 high-quality randomised controlled trials with 4328 patients were ultimately included. SBMs per week increased significantly after using 1\u2009mg (OR: 2.40, 95% CI 1.32 to 4.37), 2\u2009mg (OR: 2.55, 95% CI 1.93 to 3.36) and 4\u2009mg (OR: 2.51, 95% CI 1.92 to 3.28) prucalopride. Bayesian analysis demonstrated 1\u2009mg dose obtained the maximum SBMs per week (OR: 3.31, 95% credible interval 1.72 to 6.16, probability rank=0.70) indirectly compared with 2\u2009mg and 4\u2009mg doses. TEAEs were higher significantly in 2\u2009mg (risk ratio (RR): 1.20, 95% CI 1.09 to 1.33) and 4\u2009mg (RR: 1.14, 95% CI 1.07 to 1.22) prucalopride.
