Diagnostic value of somatosensory evoked potentials for paroxysmal sympathetic hyperactivity: a retrospective cohort 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
Purpose: This study aimed to investigate the diagnostic value of somatosensory evoked potentials (SEPs) in patients with paroxysmal sympathetic hyperactivity (PSH) and to identify independent predictors of the condition. Methods: A retrospective cohort study was conducted on 123 patients with prolonged disorders of consciousness (PDOC) admitted to the Critical Care Rehabilitation Department of Nanjing Jiangning Hospital between August 2022 and August 2024. Patients were classified into PSH-positive (PSH+) and PSH-negative (PSH-) groups according to the Paroxysmal Sympathetic Hyperactivity Assessment Measure (PSH-AM). Demographic, clinical, and SEPs parameters were collected. Univariate and multivariate logistic regression analyses were employed to examine the association between these variables and PSH. The predictive performance was evaluated using receiver operating characteristic (ROC) curve analysis. Results: A total of 123 patients with prolonged disorders of consciousness were enrolled in the study. Among these, 34 patients (27.64%) were classified into the PSH + group and 89 patients (72.36%) into the PSH - group. Multivariate logistic regression analysis identified younger age (OR = 0.96, 95% CI: 0.92-0.99, Conclusion: A reduced N20-P25 amplitude may serve as an independent and objective electrophysiological biomarker for the early prediction of PSH. In combination with younger age and male patient, it contributes to the identification of high-risk populations and offers valuable guidance for clinical management.
