Predictive value of erythrocyte sedimentation rate, albumin and CRP for infection risk in elderly rheumatoid arthritis patients undergoing treatment.

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
objectiveTo develop a predictive model for infection risk in elderly rheumatoid arthritis (RA) patients using laboratory markers, particularly erythrocyte sedimentation rate (ESR), albumin (ALB), and C-reactive protein (CRP).
methodsThis retrospective study included 452 elderly RA patients admitted to the Hospital of Chengdu University of Traditional Chinese Medicine between January 2021 and June 2024. The patients were randomly divided into a training group (271 patients) and a validation group (181 patients) at a 6:4 ratio. Key clinical and laboratory data were collected, including ESR, ALB, CRP, and others. Lasso regression and multivariable logistic regression were employed to identify infection-related factors. Model performance was evaluated using receiver operating characteristic (ROC) curves, calibration curves, and decision curve analysis (DCA).
resultsThe study identified ALB<33.75 g/L, CRP≥32.75 mg/L, and ESR≥51.50 mm/h as independent risk factors for infection in elderly RA patients. A predictive model incorporating these three markers demonstrated high diagnostic accuracy, with an AUC of 0.909 in the training group and 0.880 in the validation group. DCA further confirmed the clinical utility of the model.
conclusionsThis study successfully developed a predictive model combining ESR, ALB, and CRP to assess infection risk in elderly RA patients. This model has significant potential to enhance early infection detection and support clinical decision-making, offering a valuable tool for managing this vulnerable population.
