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.
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
introductionAccidental hypothermia (AH) can occur in mild-to-severe cases; however, its management is crucial in severe cases as it can cause ventricular fibrillation and lead to death. Among various rewarming therapies for AH, endovascular catheter rewarming has been the focus of recent studies as a minimally invasive alternative to invasive internal rewarming, such as extracorporeal membrane oxygenation (ECMO). However, no study has demonstrated the efficacy and safety of endovascular catheter rewarming therapy. This study aimed to validate the efficacy and safety of endovascular catheter rewarming for patients with AH. METHODS AND ANALYSES: The intensive care with endovascular catheter rewarming in accidental severe hypothermia (ICE-CRASH II) study is a multicentre, randomised study of patients with AH. This study will include patients with AH (age ≥65 years, core temperature <30°C) with preserved circulation and a target sample size of 88. Patients with cardiac arrest (CA), those who have undergone hospital transfers, and those in whom a central venous catheter could not be accessed through the femoral vein will be excluded from the study. Patients will be assigned to either the endovascular catheter plus conventional rewarming group or the conventional rewarming group based on stratified-substitution block randomisation. Patients will be followed up for 30 days after the initiation of the intervention or until discharge. The primary outcome will be to compare the percentage of patients achieving a rewarming rate ≥1.5°C/hour between the endovascular catheter plus conventional rewarming group and the conventional rewarming group. ETHICS AND DISSEMINATION: This study was approved by the Hokkaido University Certified Review Board (approval number: 024-00013). Written informed consent will be obtained from all the participants or their legally acceptable representatives. The results will be disseminated through publications and presentations. TRIAL REGISTRATION NUMBER: Japan Registry of Clinical Trials (jRCT1012240051).
