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

objectivesThis study investigated the relationship between the glucose-to-potassium ratio (GPR) and intensive care unit (ICU) delirium as well as with all-cause mortality.

methodsWe analyzed 32,025 first-time ICU patients from MIMIC-IV v3.1, categorized by GPR quartiles. Multivariable logistic regression, restricted cubic splines (RCS) were used to analyze the GPR-delirium relationship. The optimal GPR cutoff was determined using ROC analysis. Propensity score matching (PSM) was performed to control confounders. Cox models assessed associations with 28-, 90-, and 365-day mortality. Mediation analysis evaluated delirium's role.

resultsDelirium incidence was 16.09% (n=5,152) and increased with GPR (Q1:13.93% vs. Q4:21.71%, P<0.001). After adjustment, Q4 had 58% higher delirium risk (OR=1.58, 95% CI 1.43-1.75). RCS showed a nonlinear positive association (P<0.001). The optimal GPR cutoff was 1.837 (AUC=0.829). After PSM, high GPR (≥1.837) remained a significant predictor (OR=1.43, 95% CI 1.24-1.64). High GPR was associated with high mortality at 28, 90, and 365 days (HR=1.17, 95% CI 1.08-1.28; HR=1.10, 95% CI 1.03-1.18; HR=1.11, 95% CI 1.05-1.18). Delirium mediated 19.067%, 32.218%, and 26.197% of the GPR-mortality relationship at these time points.

conclusionsElevated GPR is associated with higher delirium risk and short- and long-term mortality in ICU patients, with delirium partially mediating this relationship. GPR may serve as a practical biomarker for early risk stratification.
