Vocal biomarkers for geriatric health assessment: a scoping review protocol
Amir-Behghadami M, Gholipour K, Mohammadzadeh Z.. BMJ open, 2026-02-23
Topic: Risk, prevention and care in population studies
Plain-language summary
The human voice has emerged as a promising digital biomarker, with vocal characteristics reflecting physiological and cognitive changes associated with conditions like dementia and Parkinson's disease. The results will be synthesised and presented narratively, accompanied by summary tables, charts and figures to address each research question. They concluded that since the review involves only analysis of existing literature without direct patient involvement or clinical procedures, it meets the relevant ethical standards. Results from the review will be shared through peer-reviewed journals and conference presentations to provide valuable insights for researchers, clinicians and policymakers on the use of audio-based biomarkers in older adults.

How this study scored 74/100
Published in a peer-reviewed journal, and it is a meta-analysis pooling many studies. Scored zero for sample size, effect reported and studied in people because the record does not state it. We have no data on journal's citation record, times cited, citations per year, impact for its field and year, cited by studies here, still being cited, senior author's track record, institution's track record and multicenter collaboration, so those were left out: it earned 43 of the 58 points we could judge it on, which is 74 out of 100.
