1 · What the graph read from 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.

2 · The registry

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

The current study examines vowel intelligibility across interactive and non-interactive situations for individuals with dysarthria secondary to amyotrophic lateral sclerosis (PALS). The vowel space of these speakers is often characterized by centralization and lowering, negatively affecting intelligibility. In two experiments, listeners identified vowels produced by PALS in habitual speech (non-interactive), clear speech (non-interactive), and interactive matching. Clear speech and interactive matching elicited more intelligible vowels than habitual speech. Interactive matching productions were equal to or more intelligible than clear speech productions depending on vowel. These data represent a preliminary step to understanding how the dynamics of communicative interaction may shape vowel intelligibility.
