Development and validation of a predictive model for 30-day mortality in adult bacterial meningitis: a retrospective cohort study.
Article in Frontiers in medicine, 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
Background: Bacterial meningitis continues to carry significant mortality despite advances in antimicrobial therapy. Early identification of high-risk patients remains challenging in clinical practice. Methods: We conducted a retrospective analysis of 277 adult patients with bacterial meningitis admitted between 2016 and 2024. Patients were randomly allocated to training ( Results: The overall 30-day mortality rate was 29.2% (81/277). In multivariate analysis, five independent predictors emerged: age [hazard ratio (HR) 1.04, 95% confidence interval (CI): 1.01-1.08], neurological complications (HR 2.31, 95% CI: 1.12-4.78), multidrug-resistant (MDR) infection (HR 3.15, 95% CI: 1.42-6.99), cerebrospinal fluid neutrophil percentage (HR 1.03, 95% CI: 1.01-1.05), and serum C-reactive protein (HR 1.12, 95% CI: 1.03-1.22). The nomogram demonstrated good discrimination with AUCs of 0.851 (95% CI: 0.793-0.909) in the training cohort and 0.814 (95% CI: 0.715-0.914) in validation. Decision curve analysis confirmed clinical utility across a wide probability threshold range. Conclusion: Our validated prediction model incorporating readily available clinical and laboratory parameters provides accurate risk stratification for adult bacterial meningitis patients. This tool may assist clinicians in identifying high-risk individuals who could benefit from more intensive monitoring and treatment strategies.
