Trial report in Journal of the American Heart Association, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT06202209 (The Impact of Autonomic Function on Recurrence Following Circumferential Pulmonary Vein Ablation for Atrial Fibrillation), which is not on this map. Cited by 20 papers, 1 of them a synthesis that pooled it.

1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

Abstract

Background The natural history of autonomic alterations following catheter ablation of drug-refractory paroxysmal atrial fibrillation is poorly defined, largely because of the historical reliance on non-invasive intermittent rhythm monitoring for outcome ascertainment. Methods and Results The study included 346 patients with drug-refractory paroxysmal atrial fibrillation undergoing pulmonary vein isolation using contemporary advanced-generation ablation technologies. All patients underwent insertion of a Reveal LINQ (Medtronic) implantable cardiac monitor before ablation. The implantable cardiac monitor continuously recorded physical activity, heart rate variability (measured as the SD of the average normal-to-normal), daytime heart rate, and nighttime heart rate. Longitudinal autonomic data in the 2-month period leading up to the date of ablation were compared with the period from 91 to 365 days following ablation. Following ablation there was a significant decrease in SD of the average normal-to-normal (mean difference versus baseline of 19.3 ms; range, 12.9-25.7;
