Application of Clock Drawing Test in Screening Cognitive Function Impairment of Parkinson's Disease
Bibliographic record
Abstract
Objective To explore the application of clock drawing test(CDT)in screening cognitive function impairment of Parkinson's disease(PD).Methods Forty-three patients with PD were involved into the study,comprehensively evaluated with the series of neuropsychological test including CDT,mini-mental state examination(MMSE),Montreal cognitive assessment(MoCA)and other tests.Results The CDT score of twenty-one patients were less than 3(48.8%).The main abnormality of CDT was in the digital part(34.9%)and the finger part(39.5%).No difference was found in age,disease duration,education years and UPRDS-III between the CDT normal group and the CDT abnormal group(P0.05),while the difference of Hoehn Yahr scale,MMSE and MoCA between two groups were significant(P0.01).CDT was positively related with MoCA and MMSE(P0.01),and negatively related with Hoehn Yahr scale,while not related with age,disease duration,education and UPRDS-III years(P0.05).Conclusion CDT is a convenient and sensitive cognitive screening test for cognitive function impairment of Parkinson's disease.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
