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
Objective: Diabetic patients exhibit increased susceptibility to infections and a higher risk of progression to sepsis. This study aimed to develop a sepsis risk prediction model specifically for diabetic patients with acute infections. Methods: In this retrospective, single-center study, we enrolled 604 hospitalized diabetic patients with acute infections. A propensity score-matched cohort (103 sepsis cases vs 412 non-sepsis controls) was constructed. A predictive model integrating clinical manifestations and laboratory parameters was developed by first pre-selecting variables via a bootstrap-based penalized regression process, followed by Firth penalized logistic regression. The model underwent internal validation and subgroup analysis, with its performance compared against the National Early Warning Score 2 (NEWS2), Systemic Inflammatory Response Syndrome (SIRS), and Quick Sequential Organ Failure Assessment (qSOFA) scoring systems in terms of discrimination, calibration, clinical utility, and cost-effectiveness. Results: The final model incorporated five predictors: temperature dysregulation, nausea or vomiting, fatigue, albumin, and procalcitonin. It demonstrated excellent predictive performance, with a corrected AUC of 0.915 and a calibration slope of 1.022. Subgroup analyses confirmed consistent performance across all subgroups, and the model significantly outperformed NEWS2, SIRS, and qSOFA in predictive accuracy, clinical applicability, and cost-effectiveness. Conclusion: The host-clinical integrated model developed in this study could provide a novel tool for early sepsis risk warning in diabetic patients with acute infections. This approach of integrating host characteristics with the pathophysiology of sepsis may offer new insights for sepsis risk early warning in specific populations. However, external validation in independent cohorts is needed before clinical implementation.
