Abstract

fetched live from OpenAlex

Objective To assess Montreal cognitive assessment(MoCA)in different ways and MoCA's latent factorial structure with confirmatory factor analysis(CFA).Methods The MoCA and Mini Mental State Examination(MMSE)were taken to all subjects(thirty-two patients with AD,forty-two patients with MCI and twenty-nine normal controls)to compare the sensitivity of the MMSE and MoCA in screening the MCI、to assess the Internal consistency and correlation between the scores of MoCA and MMSE and to perform confirmatory factor analysis.Results The Sensitivity to distinguish MCI and AD were 81.0% and 100% respectively and MMSE were 20.0% and 93.8%.There was high correlation between the scores of MoCA and MMSE(r=0.911,P0.001).The measures of reliability concerning the MoCA showed good internal consistency(Cronbach's α=0.954).CFA results showed very good/excellent adjustment indexes.Conclusions In a clinical population,the MoCA is a valid and reliable instrument with good properties and good factorial structure.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
