Question Use in Conversational Discourse Among Individuals With and Without Traumatic Brain Injury.
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
purposeThis study investigated patterns of question use in conversation among individuals with traumatic brain injury (TBI) by analyzing the frequency, types, and social actions of the questions.
methodQuestions from conversational discourse transcripts of 54 individuals with TBI and 49 age- and education-matched healthy controls with no brain injury (NBI) were extracted and coded by question type. Coded question types included either formal (polar [
resultsBoth analytical approaches revealed that individuals with TBI showed significantly reduced use of polar questions when compared to individuals with NBI. Individuals with TBI showed higher proportions of content questions (32.5% vs. 20.3%), functional questions (17.6% vs. 10.2%), and questions used to initiate repair in conversations (10.4% vs. 4.2%), although these differences were not statistically significant after correction for multiple comparisons.
conclusionsIndividuals with TBI produced a significantly lower proportion of polar questions than individuals with NBI. Group differences in other question types and the frequency of repair-oriented questions did not remain statistically significant after correction for multiple comparisons. Future experimental study is warranted to confirm the question use patterns and investigate the functional impact of these differences on conversation effectiveness.
