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
Purpose: To evaluate the efficacy of an intelligent closed-loop warming system compared with conventional warming methods in preventing perioperative hypothermia and improving postoperative recovery in patients undergoing video-assisted thoracoscopic surgery (VATS). Patients and Methods: A total of 118 adult patients scheduled for elective VATS were randomly assigned to the conventional warming group (n = 59) or the intelligent closed-loop warming group (n = 59). Conventional warming management employed an underbody warming blanket, supplemented with blood and fluid warming when core temperature fell below 36.0°C. The intelligent closed-loop warming system utilized wireless sensors and an automated feedback-controlled warming unit to maintain core temperature between 36.5°C and 37.0°C. Core temperature was continuously monitored from anesthesia induction to post-anesthesia care unit (PACU) discharge. The primary outcome was the incidence of perioperative hypothermia (core temperature < 36.0°C). Secondary outcomes included mean and minimum intraoperative temperature, extubation time, PACU temperature, postoperative complications, length of hospital stay (HLOS), and hospitalization cost. Results: Perioperative hypothermia occurred in significantly fewer patients in the intelligent group than in the conventional group (25.4% vs. 76.3%, Conclusion: The intelligent closed-loop warming system effectively prevents perioperative hypothermia and enhances postoperative recovery in VATS patients. It provides precise thermal regulation and better clinical outcomes, supporting its application in perioperative temperature management.
