Preoperative geriatric nutritional risk index as a predictor of intraoperative hypothermia in esophageal cancer surgery.
Article in Asia-Pacific journal of oncology nursing, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Objective: Esophageal cancer is life-threatening, and esophagectomy patients have a high incidence of intraoperative hypothermia (linked to adverse postoperative outcomes), with no stable predictive indicator available. The Geriatric Nutritional Risk Index (GNRI), a validated tool for predicting cancer prognosis/complications, has not been studied for its association with intraoperative hypothermia in esophageal cancer surgery. This study evaluated their association and GNRI's predictive efficacy. Methods: A retrospective analysis of 676 esophageal cancer surgery patients (Fujian Provincial Cancer Hospital, July 2022-February 2025) was conducted. Logistic regression assessed GNRI-hypothermia association, restricted cubic splines (RCS) explored nonlinear relationships, and receiver operating characteristic (ROC) curves evaluated predictive efficacy. Intraoperative hypothermia was defined as core temperature ≤ 36°C. Results: Among the 676 patients, the incidence of intraoperative hypothermia was 41.4%. Multivariate logistic regression analysis indicated that patients in the nutritional risk group (GNRI < 98) had a significantly higher risk of intraoperative hypothermia compared to those without nutritional risk (GNRI≥ 98). The adjusted odds ratio (OR) was 1.95 (95% confidence interval [CI]: 1.34-2.82, Conclusions: Preoperative GNRI is an independent predictor of intraoperative hypothermia in patients undergoing esophageal cancer surgery. The thresholds of 93 and 98 can serve as clinical reference points for nutritional interventions, offering a novel assessment tool for perioperative temperature management in esophageal cancer patients.
