Blood nutrition-related biomarkers for central nervous system injury rehabilitation prognosis: a retrospective study.
Article in Lipids in health and disease, 2026. 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
backgroundMalnutrition is highly prevalent among patients with central nervous system (CNS) injuries. Although nutrition-related blood biomarkers help evaluate malnutrition, their prognostic value during CNS injury rehabilitation remains unclear.
objectiveThis study aimed to evaluate the impact of nutrition-related blood biomarkers on rehabilitation outcomes in CNS injury patients.
methodsA total of 669 patients with CNS injuries admitted to a Chinese tertiary teaching hospital from December 2017 to December 2025 were enrolled. Functional outcomes were assessed using the mean relative functional gain (mRFG) of the modified Barthel index. Independent prognostic factors were identified using both univariate and multivariate analyses, including demographic and clinical characteristics, complications, and blood biomarkers. The receiver operating characteristic (ROC) curve analysis was employed to assess the optimal cutoff values for independent predictors. Findings were validated using restricted cubic spline (RCS) models, subgroup analyses, and sensitivity analyses.
resultsMultivariate analysis demonstrated that albumin (odds ratio [OR] = 0.934, P = 0.029), total cholesterol (TC, OR = 1.816, P < 0.001), and low-density lipoprotein cholesterol (LDL-C, OR = 1.580, P = 0.003) were independent predictors of functional prognosis. When grouped by cutoff values, significant differences in mRFG were observed for albumin (cutoff value = 36.35 g/L, P = 0.002), TC (cutoff value = 3.24 mmol/L, P < 0.001), and LDL-C (cutoff value = 1.89 mmol/L, P < 0.001). RCS analyses demonstrated no significant nonlinear relationships. Subgroup analyses revealed no significant effect modification by injury type, although TC showed significant positive associations in spinal cord injury and hemorrhagic stroke. A significant gender interaction was found for TC (P for interaction = 0.021), with a stronger association in males (OR = 2.43, 95% CI: 1.70–3.48).
conclusionAlbumin, TC, and LDL-C are independent predictors of functional prognosis in patients with CNS injury. Albumin is protective, while TC and LDL-C correlate with poorer outcomes. The identified cutoff values may help clinicians guide patient management and prognostic assessment.
