Association between a high Modified Nutrition Risk in Critically Ill score and 30-day mortality in critically ill adults: A retrospective cohort study.
Article in Irish journal of medical science, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundPropensity-Score matching methods are one of the statistical methods used to reduce methodological bias in studies.
aimsIn our study, we investigated the effect of m- Nutritional Risk in Critically Ill (m-NUTRIC) score on 30-day mortality using the Propensity-Score matching method.
methodPatients admitted to the ICU, who nutrition support were included in this retrospective cohort study. Patients' m-NUTRIC scores were recorded. Propensity score matching and inverse probability of treatment weighting (IPTW) based on propensity score analyses were applied to address covariate imbalances between the two m-NUTRIC groups (low and high). Decision curve analysis was used to illustrate the net benefit of employing the Boruta-adjusted and propensity score-matched models over for determining 30-day mortality. Statistical analyses utilized two-sided tests with a significance level of 0.05.
resultsThe study population consisted of a total of 599 patients. m-NUTRIC score ≥ 5 had a significantly higher 30-day all-cause mortality rate compared to those with a score < 5 (p < 0.001). m-NUTRIC score was found to be a strong independent predictor of 30-day mortality (HR = 1.53, 95% CI: 1.35-1.72, p < 0.001) when considered as a continuous variable. In the IPTW analysis, individuals with an m-NUTRIC ≥ 5 score had a significantly higher 30-day mortality risk (weighted-HR = 1.67, 95% CI: 1.48-1.90, p < 0.001). This association remained consistent in the propensity score matched population (p < 0.001) and in the IPTW-adjusted cohort (p < 0.001).
conclusionsThe m-NUTRIC score was effective in predicting mortality rates. This study highlights the usefulness of the propensity-matching method in such studies.
