An exploratory model of speech intelligibility for healthy aging based on phonatory and articulatory measures.
Article in Journal of communication disorders. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers, 1 of them a synthesis that pooled it.
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
purposeThe aims of the current study were to determine age-related changes to the phonatory and articulatory subsystems and to investigate an exploratory model of intelligibility for healthy aging based on phonatory and articulatory measures.
methodFifteen healthy, older adults (55-81 years) and 15 younger adults (20-35 years) participated in instrumental assessments of the phonatory (aerodynamic, acoustic) and articulatory (kinematic) subsystems. Speech intelligibility was determined by five listeners during multi-talker babble.
resultsOlder adults displayed shorter maximum phonation time, greater airflow during sentence reading, and lower cepstral peak prominence (CPP) and CPP SD. Additionally, older adults had slower tongue movement speed than younger adults. Speech intelligibility was also significantly reduced in the older group. A generalized estimating equations model combining phonatory and articulatory measures showed that CPP SD, low/high (L/H) spectral ratio mean and SD, Cepstral Spectral Index of Dysphonia (CSID), and maximum tongue movement speed were significant contributors to intelligibility changes in older individuals. While L/H mean and SD and CSID displayed an inverse relationship with intelligibility, CPP SD and maximum tongue speed displayed a direct relationship with intelligibility. DISCUSSION: Aging affects the phonatory and articulatory subsystems with implications for speech intelligibility. Phonatory cepstral/spectral measures (except mean CPP) were associated with speech intelligibility changes, suggesting that changes in voice quality may contribute to reduced intelligibility in older adults. Pertaining to articulation, slower tongue movement speed likely contributed to reduced intelligibility in older individuals.
