Fig. 1: DCTclock Scores and Subdomains in Relation to Mini-Cog Status.
From: Digital clock assessment in South Asian setting: pilot study
A Distribution of total DCTclock scores by Mini-Cog status. Dashed lines at scores of 60 and 75 indicate thresholds used in prior validation studies. B Receiver operating characteristic (ROC) curve showing the discriminatory ability of the DCTclock score to identify Mini-Cog impairment (AUC = 0.669 (95%CI: 0.580–0.758)). C Boxplot comparing total DCTclock scores between Mini-Cog impaired and unimpaired participants. Dashed lines represent key thresholds: clinical cutoffs at 60 (red) and 75 (blue), and ROC-derived optimal threshold at 38 (purple dotted). D Comparison of DCTclock subdomain scores (Command and Copy conditions) by Mini-Cog status. Domains include Drawing Efficiency, Information Processing, Motor, and Spatial Reasoning. P-values are from Wilcoxon rank-sum tests comparing impaired vs. unimpaired groups. Mini-Cog Status: □ Unimpaired = Mini-Cog total score ≥3 □ Impaired = Mini-Cog total score ≤2.
