Esophageal Temperature Monitoring during Atrial Fibrillation Ablation: A Randomized Study.
Trial report in Arquivos brasileiros de cardiologia, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT03645070 (A Prospective Randomized Study on the Effect of Oesophageal Temperature Monitoring on the Incidence of Esophageal Lesions After Left Atrial Ablation for the Treatment of Atrial Fibrillation.), which is not on this map.

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
backgroundPulmonary vein isolation (PVI) for atrial fibrillation (AF) ablation carries a risk of esophageal thermal injury (ETI), which can lead to severe complications.
objectiveTo evaluate three luminal esophageal temperature (LET) monitoring strategies and assess their effectiveness in reducing the incidence of ETI.
methodsPatients with AF were randomized into three PVI groups according to the temperature monitoring strategy: no LET monitoring (Group 1), LET monitoring with a single-sensor probe (SSP) thermometer (Group 2), and LET monitoring with a multisensor probe (MSP) thermometer (Group 3). In Group 1, AF ablation was performed at a fixed power of 20 W on the left atrial posterior wall. In Groups 2 and 3, AF ablation power was titrated based on LET measurements, with a cutoff temperature of 37.5 °C. Each group included 20 patients. A two-sided p-value <0.05 was considered statistically significant. The trial was registered on ClinicalTrials.gov (#NCT03645070) and International Clinical Trials Registry Platform (#RBR-2yvgyf).
resultsAll patients underwent PVI and esophagogastroduodenoscopy. No ETI was observed in patients monitored with an MSP thermometer. In contrast, five patients without LET monitoring and six patients monitored with an SSP thermometer developed ETI (p=0.006). Higher temperatures were recorded with an MSP thermometer (37.9 vs. 38.45 °C, p=0.018). There were no significant differences in PVI duration or total radiofrequency application time (p=0.250 and p=0.253, respectively).
conclusionsLET monitoring with an MSP thermometer during PVI significantly reduces the incidence of ETI compared to no monitoring or SSP monitoring. Implementing advanced LET monitoring strategies may enhance patient safety without compromising procedural efficiency.
