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

introductionAtrio-esophageal fistula is a rare but devastating complication from thermal esophageal injury during pulmonary vein isolation (PVI). Modifying ablation energy delivery and placement of esophageal temperature probes (ETPs) have been employed to mitigate the risk of thermal esophageal injury. Our study sought to compare the effects of return electrode location, insulation of the ETP, and use of high-power short-duration (HPSD) ablation on esophageal temperature, ETP temperature measurement, and thermal lesion dimensions.

methodsA myocardial phantom gel model using thermochromic material was used to approximate the atrio-esophageal environment. Irrigated ablations were performed at 30 W/20 s (low-power long duration [LPLD]) and 50 W/5 s (HPSD) with variation of return electrode position and insulation of the ETP. Temperatures were continuously logged, and digital photography with in-house software was performed to examine lesion dimensions.

resultsDistant placement of a return electrode compared to proximal placement decreased peak esophageal temperature (T

conclusionHPSD settings, insulation of the ETP, and a distant return electrode placement minimized esophageal heating. These strategies may reduce thermal injury to the esophagus during radiofrequency ablation.
