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

backgroundInadvertent perioperative hypothermia is associated with adverse cardiovascular outcomes, but adequately powered trials using high-sensitivity troponin endpoints is lacking. The SAGE trial evaluates whether an intelligent, closed-loop thermoregulation strategy reduces myocardial injury after noncardiac surgery (MINS) in high-risk elderly patients.

methodsThis prospective, multicenter, parallel-group, randomized controlled superiority trial conducted at seven tertiary hospitals in China. Participants aged ≥65 years scheduled for elective gastrointestinal tumor resection under general anesthesia are randomly assigned (1:1) to intelligent closed-loop warming (target 36.8 °C, upper limit 37.0 °C) or routine thermal management (active warming only if core temperature ≤35.5 °C). The primary outcome is the incidence of MINS within the first 2 postoperative days , adjudicated using high-sensitivity troponin thresholds per AHA criteria. Secondary outcomes include surgical site infection, transfusion requirement, hypothermia burden, emergence delirium, delayed emergence, and postoperative shivering. With 695 participants per group (total 1,390, accounting for 10% dropout), the trial has 80% power at a one-sided significance level of 0.05 to detect a 6 absolute percentage point reduction in MINS (12% to 6%) with a superiority margin of -2 percentage points. DISCUSSION: The SAGE trial is designed to generate new evidence on the relationship between intraoperative hypothermia exposure and postoperative cardiovascular complications. It will evaluate whether closed-loop targeted normothermia reduces myocardial injury and will explore hypothermia exposure thresholds that may inform individualized perioperative management for geriatric surgical patients.
