Beyond NACC's Uniform Data Set for cognition: the impact of additional items on measurement precision.
Article in Alzheimer's & dementia : the journal of the Alzheimer's Association, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 1 paper.
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
introductionWe sought to determine the implications of integrating additional cognitive test items beyond the items of the Uniform Data Set (UDS) administered by Alzheimer's Disease Research Centers (ADRCs).
methodsWe considered the UDS 1&2 and UDS 3 cognitive batteries alone ("UDS-only") and compared them to batteries augmented with additional items ("UDS-augmented") administered by the University of Pittsburgh, ADRC. We used confirmatory factor analyses to co-calibrate and harmonize three cognitive domains (memory, executive functioning, and language). Then we compared the UDS-only and UDS-augmented with respect to measurement precision, sample sizes required to detect 25% differences in rates of decline, and association between baseline scores and the hazard of converting from mild cognitive impairment to AD dementia.
resultsUDS-augmented substantially enhanced measurement precision across all cognitive domains for UDS 1&2 and UDS 3. DISCUSSION: There is substantial value in integrating item content beyond the UDS. HIGHLIGHTS: We considered items from the UDS 1&2 and UDS 3 cognitive batteries alongside augmented site-specific content for the memory, executive functioning, and language domains. Augmented scales improved measurement precision in each case. As expected, improved measurement precision facilitated better performance for each scale. It would be useful to integrate multiple sources of cognitive data into comprehensive estimates of domain performance.
