Aerodynamic Demand Responses to the Fluid Interval Test for Voice: A Laryngeal Diadochokinetic Vocal Loading Task.
Article in Journal of speech, language, and hearing research : JSLHR, 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
introductionVocal loading tasks are useful for studying vocal demand responses
methodParticipants (
resultsInstantaneous LDDK rate did not change significantly within trials or intervals-unlike the aerodynamic variables, which exhibited task- and time-dependent changes. Large increases in mean airflow and expiratory volume within trials were characteristic of the resisted FIT-V
conclusionsVoice users actively modulated their aerodynamic output at multiple levels throughout the FIT-V tasks, although it is unclear whether these modulations were responsible for participants' ability to maintain rapid LDDK rates. Future work will examine how different vocal demand responses influence perceived fatigue, performance fatigability, and laryngeal pathology risk.
