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.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Background: The efficacy and safety of second catheter ablation (CA) sessions for idiopathic premature ventricular contractions (PVCs) from the same origin as the initial session remain unclear. Methods and Results: We analyzed 138 patients (median age 55 [43-68] years; 74 males [53.6%]) who underwent second CA sessions for idiopathic PVCs from the same origin category, using the Japanese Catheter Ablation Registry data collected between August 2017 and December 2020. PVC origins included 77 from the right ventricular outflow tract (RVOT) (55.8%), 8 from other right ventricular (RV) origins (5.8%), 23 from the left ventricular outflow tract (LVOT) (16.7%), and 30 from other left ventricular (LV) origins (21.7%). Acute success was achieved in 114 patients (82.6%), with significant variations by origins (RVOT: 83.1%, other RV: 75.0%, LVOT: 76.9%, other LV: 90.0%; Conclusion: Second CA sessions for idiopathic PVCs are generally safe and effective. However, additional efforts are needed to improve the LVOT and other RV origin efficacy.
