Meta-analysis of eight trials comparing ablation with medication

↵* As studies were not structured uniformly, the text under each study describes the group against which the ablation group was compared (the comparator group). The number in brackets shows mortality per year of follow-up (or % per annum).
↵† Denotes statistical significance between groups.
