Lollipop chart showing classification performance ranges for 21 studies (n = 13–336). Studies ranked by median performance with sample sizes indicated (n = X). Lines connect minimum-maximum performance ranges; points represent individual methods colored by metric (blue: accuracy; orange: AUC), with opacity indicating performance level and size scaled by sample size. Labels show min, max, and median (bold) values. Performance spans 0.45–0.95, with median values 0.62–0.94. Heterogeneity reflects dataset, protocol, and methodological variations. MCI mild cognitive impairment, AUC area under curve.
