Multi-site video-based assessment with the NACC UDS-Version 3 battery: Design and participant experience in the V-Cog study.
Trial report 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. Cited by 2 papers.
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
introductionVideo-based cognitive testing is becoming more common. The 'VCog' study aims to evaluate the validity, feasibility, and acceptability of a standardized video-administered cognitive research battery.
methodsTwelve Alzheimer's Disease Research Centers (ADRCs) administered, in randomized order, an in-person and video-adapted Uniform Data Set Version 3 (UDSv3) cognitive assessment battery to participants with normal cognition (n = 156), mild cognitive impairment (MCI; n = 230), and dementia (n = 77). Acceptability of technology and participant experience completing video testing was assessed.
resultsOf 463 participants (mean age 75.1 years, 52.5% female, and 25.5% non-White individuals), most rated video testing as easy (90.0%), convenient (95.3%) and would accept it in future visits (75.5%). Greater cognitive impairment was associated with more difficulty with setup and use of video. Staff rated most administrations as producing valid data (94.8%). DISCUSSION: Video-based research cognitive testing with an adapted UDSv3 battery is feasible and well-accepted among older adults with and without cognitive impairment. HIGHLIGHTS: The COVID-19 pandemic increased the need for video-administered cognitive assessments in Alzheimer's Disease Research Centers (ADRCs) . Feasibility, acceptability, and validity of video cognitive testing were evaluated. Participant experience and examiner evaluations of data validity were positive. Video assessment may extend the ADRCs reach to otherwise unreachable participants.
