Associations of serum glucose/potassium ratio with short-term and long-term mortality in sepsis patients: a retrospective cohort study based on the MIMIC-IV database.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
This study evaluated the prognostic value of glucose/potassium ratio (GPR) in sepsis using MIMIC-IV data (n = 31,717). Patients were stratified by GPR quartiles (Q1: <1.450 to Q4: ≥2.169). Adjusted Cox models demonstrated a dose-dependent increase in mortality in patients with higher GPR levels (P < 0.001), with the highest risk of mortality observed in Q4. Restricted cubic spline analysis revealed a U-shaped relationship between GPR and mortality (30-day optimal cutoff: 1.49). Sensitivity analyses excluding patients with diabetes, acute renal failure, or chronic liver disease confirmed the robustness of results, with consistent findings across subgroups. These findings indicate that GPR independently predicts both short-term (30/90/180-day) and long-term (1-year) mortality in sepsis, providing valuable references for risk stratification.
