Association between the geriatric nutritional risk index and all-cause mortality in older critically ill patients with community-acquired pneumonia.

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
aimThis study aimed to explore the association between the geriatric nutritional risk index (GNRI) and the risk of mortality in critically ill older patients with community-acquired pneumonia (CAP).
methodsThis retrospective study included 1924 critically ill patients with CAP from the Medical Information Mart for Intensive Care-IV3.1 (MIMIC-IV3.1) database. The participants were grouped into four groups based on GNRI levels. The clinical outcome was 30-day, 90-day, 180-day, and 1-year mortality. Cox proportional hazards regression analysis and restricted cubic spline regression were used to evaluate the association between the GNRI and clinical outcomes in critically ill older patients with CAP.
resultsA total of 1924 patients (56.9% male) were included in the study. The 30-day, 90-day, 180-day, and 1-year mortality were 37.7%, 47.7%, 54.0% and 59.1%, respectively. Multivariate Cox proportional hazards analysis showed that the GNRI was independently associated with all-cause mortality. After adjusting for confounders, GNRI remained significantly associated with both short- and long-term mortality. Restricted cubic splines revealed a linear association between GNRI and all-cause mortality in CAP patients.
conclusionOur study indicates that the GNRI has a significant association with all-cause mortality in critically ill older patients with CAP. However, further confirmation of these findings requires larger prospective studies.
