The Geriatric Nutritional Risk Index as an Alternative to the EuroSCORE II in Estimating Cardiac Surgery Risk.
Article in European journal of cardio-thoracic surgery : official journal of the European Association for Cardio-thoracic Surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
objectivesThe Geriatric Nutritional Risk Index (GNRI) was introduced to predict mortality in elderly people (age ≥ 65 years). In contrast to common risk scores for cardiac surgery, the GNRI relies on just 6 clinical parameters: age, height, weight, sex, albumin, and sodium.
methodsThis study presents a large single-centre, retrospective analysis of all consecutive patients ≥ 65 years who underwent cardiac surgery using cardiopulmonary bypass (CPB) between 2010 and 2023. Patients were stratified according to GNRI risk classes: major risk (<82), moderate risk (82 to <92), low risk (92 to ≤98), and minimal risk (>98). Receiver operating risk analyses were performed to compare the predictive power of 30-day mortality of GNRI versus the EuroSCORE II.
resultsIn total, 6712 patients were included: 52 (0.8%) patients were at major risk, 233 (3.5%) patients were at moderate risk, 506 (7.5%) patients were at low risk, and 5921 (88.2%) patients were at minimal risk. The GNRI had the same predictive power for 30-day mortality as the EuroSCORE II (AUC = 0.75 vs AUC = 0.71, P = .051). Notably, when adjusted for the type of surgery, GNRI reached an AUC = 0.77 and did statistically not differ from the EuroSCORE II (P = .6). The Hosmer-Lemeshow test indicated good calibration for both the GNRI model (P = .301) and the adjusted GNRI model (P = .619) and revealed P < .0001 for the EuroSCORE II.
conclusionsThe GNRI demonstrates predictive power for all-cause 30-day mortality comparable to the EuroSCORE II in a real-world patient cohort. GNRI offers a substantial simplification of risk estimation in patients undergoing cardiac surgery with CPB.
