A Comparison of Four Selected Acoustic Measures in Detecting Voice Quality Changes With Botulinum Toxin Treatment in Adductor-Type Laryngeal Dystonia.
Article in American journal of speech-language pathology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
purposeAdductor-type laryngeal dystonia (AdLD) is a voice disorder with substantial negative effects. The current standard treatment is botulinum toxin (BoNT) injections, with novel treatments on the horizon. The aim of this study was to determine the sensitivity of selected acoustic measures to measure voice quality change from pre-BoNT to the participants' perceived maximum benefit from BoNT.
methodTwenty-three participants with AdLD underwent acoustic recordings at pre-BoNT and a subset of 12 participants during the participants' perceived maximum benefit from BoNT. Four acoustic measures were employed: (a) cepstral peak prominence-smoothed (CPPS) estimated in Praat, (b) the cepstral spectral index of dysphonia (CSID), (c) percent creak (%creak), and (d) sharpness (a measure of vocal strain). The four measures were also compared with listener ratings and Voice Handicap Index (VHI-10) scores.
resultsThe CPPS, CSID, and %creak measures showed significant treatment-related change (
conclusionsBased on these results, CPPS, CSID, and %creak showed utility in assessing voice quality change from pre- to post-BoNT treatment in those with AdLD, with some differences across measures. Future research with novel treatments for AdLD may benefit from utilization of these measures including comparison of effect sizes with degree of improvement from BoNT outcomes.
