1 · What the graph read from it

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.

2 · The registry

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

objectiveThis study aimed to investigate the association between the Prognostic Nutritional Index (PNI) and 90-day mortality among patients with sepsis.

methodsWe conducted a retrospective cohort study utilizing data from the MIMIC-IV database for patients diagnosed with sepsis. Covariates were selected using Cox regression models. The association between PNI and 90-day mortality was assessed using multivariable Cox proportional hazards models. We further examined the potential nonlinear relationship using restricted cubic spline(RCS) analysis. Kaplan-Meier survival curves were plotted for these groups, and the differences in 90-day survival rates were compared using the log-rank test.

resultsA total of 5,786 septic patients were included in the final analysis. The overall 90-day mortality rate after ICU admission was 35.0% (n = 2,027). In the fully adjusted Cox model, a higher PNI was associated with a reduced risk of 90-day mortality. Specifically, for each one-unit increase in PNI, the risk of 90-day mortality decreased by 1% (adjusted HR = 0.99, 95% CI: 0.98 ~ 1.00, P = 0.004). The RCS analysis revealed a significant nonlinear relationship between PNI and 90-day mortality (P

conclusionPNI demonstrates a significant nonlinear inverse association with 90-day mortality in patients with sepsis. These findings suggest that PNI could serve as a valuable prognostic tool. Clinicians may use PNI to identify high-risk patients and implement targeted interventions to potentially improve clinical outcomes.
