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
The link between serum glucose-potassium ratio (GPR) and mortality in critically ill toxic encephalopathy (TE) patients is not well defined. This study has aimed to clarify the effect of GPR fluctuations on TE mortality. A total of 3,462 TE patients with TE requiring ICU care were selected from the Medical Information Mart Intensive Care (MIMIC-IV) database. Patients were categorized into three groups based on GPR tertiles: Tertile 1 (n = 1154, range 0.103-1.442), Tertile 2 (n = 1153, range 1.444-1.966), and Tertile 3 (n = 1155, range 1.967-12.937). The primary outcomes studied were 28-day and 90-day all-cause mortality (ACM). To analyze the relationship between GPR and outcomes, we employed Cox regression models adjusted for multiple covariates and restricted cubic splines to explore the potential non-linear association. The 3,462 - patient cohort had a mean age of 67.7 ± 16.6 years, with 58.2% male. The 28-day and 90-day ACM were 21.9% and 31.2%, respectively. Multivariate adjusted analysis showed no overall GPR-ACM correlation at 28 and 90 d. Regarding different groups, with T2 as the reference group (Ref), for 28-day ACM, the adjusted hazard ratio (HR) of the T1 was 1.20 (95% Confidence Interval [CI]: 1.00-1.44, p ≡ P = 0.049), and that of T3 group was 1.22 (95% CI: 1.01-1.47, P = 0.035). For 90 - day ACM, the adjusted HR of the T1 was 1.19 (95% CI: 1.02-1.39, P = 0.023), and the T3 was 1.20 (95% CI: 1.03-1.40). The correlation between the GPR lesvel and ACM was U-shaped association. The left and right - hand side effect sizes at the inflection point (1.65) were 0.472 (HR: 0.472, 95% CI 0.306-0.728, P < 0.001) and 1.127 (HR: 1.127, 95% CI 1.032-1.229, P = 0.0075). Sensitivity analysis was stable. Our findings have revealed a U-shaped relationship between GPR levels and ACM in critically ill patients with TE. Close attention should therefore be paid to this issue in order to improve patient care.
