Quantitative susceptibility mapping and MRS-based multimodal machine learning for early Parkinson's disease classification.
Article in NPJ Parkinson's 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
Parkinson's disease (PD) is a complex, progressive neurodegenerative disorder characterized by high heterogeneity and diagnostic challenges in its early stages. This study aimed to develop and validate a multimodal machine learning model for early PD detection by integrating neurochemical metabolites and QSM-based radiomic features from multicenter PD cohorts. Several model architectures, including Random Forest, Support Vector Machine, eXtreme Gradient Boosting (XGBoost), and Light Gradient Boosting Machine, were evaluated for comparing appropriate methods. The XGBoost model demonstrated superior predictive performance, achieving AUC values of 0.984 and 0.973 in the training and test cohorts, respectively. Feature importance analysis identified key diagnostic biomarkers using SHapley Additive exPlanations (SHAP) and enhanced model interpretability. This study can provide new insights into the neurobiological mechanisms underlying early PD.
