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: Steam pop is a major safety concern in radiofrequency ablation. The temperature-flow control (TFC) mode may mitigate this risk by precisely monitoring tissue temperature. Objective: This study compared the safety and efficacy of TFC vs power control (PC) under ablation index (AI) guidance, focusing on steam pop incidence and lesion characteristics. Method: In vivo experiments were conducted in 9 swine, with atrial ablations performed under AI control at 500-600 and ventricular ablations at 550-650. Procedural parameters were recorded, and lesion characteristics and steam pops were assessed pathologically. Result: A total of 258 atrial and 117 ventricular ablations were performed in 9 pigs, of which 227 atrial and 102 ventricular ablations met the inclusion criteria. In both chambers, contact force was comparable between TFC and PC groups, but the ablation time was significantly longer with TFC ( Conclusion: TFC achieved lesion sizes similar to PC but significantly reduced steam pops at the same AI level, suggesting improved procedural safety.
