Association between the lactate to creatinine ratio and hospital mortality in patients with pediatric sepsis: a cohort study.
Article in Pediatric research, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundThe relationship between lactate to creatinine ratio (LCR) and prognosis in pediatric sepsis is poorly understood. Our study aimed to investigate the association between LCR and hospital mortality in pediatric sepsis patients.
methodsA retrospective cohort study of 4379 patients with pediatric sepsis, categorized by LCR quartiles, was performed. The association between LCR and hospital mortality was investigated using univariate and multivariate logistic regression models, as well as subgroup and sensitivity analyses. Restricted cubic splines were employed to explore non-linear relationships, and a two-piece logistic proportional hazards model was constructed for both sides of the inflection point.
resultsThe overall hospital mortality rate for pediatric sepsis was 9.6%. Following adjustment for relevant covariates, a positive correlation between LCR and hospital mortality was observed. A nonlinear relationship between the baseline LCR and the risk of hospital mortality was identified, with LCR < 0.780 associated with a significantly higher risk. Beyond the LCR turning point of 0.780, the risk did not substantially increase.
conclusionsThe study revealed a nonlinear relationship between the LCR and hospital mortality in children with sepsis. When the LCR is less than 0.780, hospital mortality rises drastically as the LCR advances. IMPACT: This research delves into the non-linear correlation between the lactate to creatinine ratio (LCR) and hospital mortality in pediatric sepsis patients. It identifies a critical threshold of LCR < 0.780 linked to higher mortality rates. This study presents the first comprehensive analysis of LCR's significance in pediatric sepsis, suggesting it as a potential biomarker for risk assessment and clinical decision-making. The implications of these findings could potentially lead to improved treatment strategies, ultimately decreasing hospital mortality in children with sepsis by optimizing lactate and creatinine management.
