Effect of Preoperative Geriatric Nutritional Risk Index on Prognosis in Patients after Surgery for Lower Gastrointestinal Perforation.

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
introductionGeriatric Nutritional Risk Index (GNRI) is a reliable index derived from serum albumin levels, height, and weight. Although various prognostic factors have been studied, the effect of preoperative nutritional status on surgical outcomes remains unexplored. This study aimed to evaluate the efficacy of the GNRI in predicting postoperative outcomes of lower gastrointestinal perforation.
methodsEighty patients treated at our institution between January 2016 and December 2022 were retrospectively analyzed. This study primarily focused on the correlation between preoperative GNRI and two key outcomes: postoperative hospital stay duration and 1-year mortality rate.
resultsOur findings revealed a significant association between low GNRI scores and increased 1-year mortality (odd ratio 4.0, 95% confidence interval [CI] 1.1-16, p = 0.025). Kaplan-Meier analysis and log-rank test showed that patients in the low GNRI group had markedly poorer overall survival rates than those in the high GNRI group (12-month survival rate 0.88 [95% CI: 0.75-0.95] vs. 0.65 [95% CI: 0.47-0.78]; p = 0.018). Additionally, both univariate and multivariate analyses indicated that lower GNRI scores were associated with prolonged hospital stays.
conclusionWe showed that a low GNRI score was associated with high mortality and prolonged hospital stay after emergency surgery for lower gastrointestinal perforation.
