Preoperative Nutritional Index as a Predictor of Pulmonary Infection and Mortality in Liver Transplant Patients.
Article in Annals of transplantation, 2025. 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
BACKGROUND Malnutrition has been linked to unfavorable outcomes in patients undergoing living donor liver transplantation. However, the utility of the preoperative prognostic nutritional index (PNI) as a predictor for postoperative pulmonary infections and in-hospital deaths remains uncertain. The current study aimed to assess the predictive utility of preoperative PNI in patients who undergo liver transplantation. MATERIAL AND METHODS A total of 177 patients who received deceased donor liver transplants from January 2020 to June 2021 were retrospectively enrolled. The potential predictive factors for postoperative pulmonary infection and in-hospital mortality were identified using univariate and multivariate analyses, and a predictive model was created, with the predictive performance assessed using the area under the receiver operating characteristic curve (AUC). RESULTS Of 177 included patients, the prevalence of postoperative pulmonary infection and in-hospital mortality was 46 (25.99%) and 25 (14.12%), respectively. Multivariate analysis indicated that preoperative normal PNI was associated with a reduced risk of postoperative pulmonary infection compared with low PNI (OR: 0.21; 95% CI: 0.09-0.49; P=0.001), and the predictive value of preoperative PNI on subsequent postoperative pulmonary infection was moderate, with an AUC of 0.66 (95% CI: 0.59-0.73). Furthermore, we noted preoperative normal PNI was associated with a reduced risk of in-hospital mortality (OR: 0.23; 95% CI: 0.08-0.70; P<0.001), and the predictive value of preoperative PNI on in-hospital mortality was mild, with an AUC of 0.65 (95% CI: 0.56-0.73). CONCLUSIONS Preoperative PNI was significantly associated with postoperative pulmonary infection and in-hospital mortality, and the predictive value of the PNI was moderate.
