Construction and validation of a prediction model for short-term mortality risk in elderly patients with sepsis: a retrospective study.

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
backgroundThis study aims to investigate the risk factors affecting short-term mortality in elderly patients with sepsis and a nomogram model was constructed.
methodsA retrospective collection was performed on clinical data of 1116 elderly patients (≥ 65 years) with sepsis hospitalized from January 2014 to December 2023. Patients were divided based on 30-day mortality: death group (392 cases) and survival group (724 cases). Differences in various biochemical indicators were compared, and Cox regression analysis was used to identify independent risk factors. The model's performance was evaluated using receiver operating characteristics (ROC) and Kaplan-Meier curves.
resultsUnivariate and multivariate Cox survival analysis were utilized to explore the risk factors for short-term mortality in elderly patients with sepsis. The analysis exhibited a significant association of age, procalcitonin, antiarrhythmic drugs, vasopressors, and albumin with patient survival time. Group differences in vitamin C positivity were observed, but this variable was not included in the prediction model. The nomogram model, demonstrated high diagnostic accuracy (C-index 0.790). Patients were divided into the high-risk group and the low-risk group based on the model's thresholds, showing significantly shorter survival times for the high-risk group.
conclusionIncreased age, use of antiarrhythmic drugs and vasopressors are independent risk factors for mortality in elderly patients with sepsis, whereas high albumin levels are protective factors. The developed nomogram provides an effective tool for predicting short-term mortality in this patient population.
