In a sub-analysis, there was no difference between the rates of pacemaker implantation calculated from multicentre and registry studies (8 studies, 6845 patients; 7%, 95% CI 5\u201310%) and single-centre studies (18 studies, 2647 patients; 7%, 95% CI 5\u20139%; P\u2009=\u20090.75). Implantation rates were similar in high-volume studies (16 studies, 9121 patients; 7%, 95% CI 5\u20138%) than in low-volume studies (10 studies, 371 patients; pooled rate: 7%, 95% CI 4\u201314%; P\u2009=\u20090.5).
