Rapid Lexical Retrieval and Executive Functioning in Very Mild Aphasia.
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. Cited by 1 paper.
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
purposeLeft-hemisphere stroke survivors who score above the Western Aphasia Battery-Revised (WAB-R) cutoff, but have self-reported aphasia, have been called not aphasic by WAB-R (NABW). Our prior work found letter fluency tasks to be sensitive to individual cases of very mild aphasia in the NABW group. Letter fluency tasks rely on both lexical retrieval and executive functioning (EF), which leaves open the question of which domain(s) are driving the impaired letter fluency in the NABW group.
methodTwenty-seven NABW and 63 healthy controls completed two-letter fluency tasks, timed picture naming, and an EF task called Antelopes and Cantaloupes (A&C). A&C is a test of switching control, semantic control, and phonological control. We used two-tailed Mann-Whitney
resultsSix measures had group differences and were correlated with the letter fluency tasks. The measures included naming reaction times (RTs), A&C measures that required rapid lexical retrieval, and an A&C measure of switching control involving lexical retrieval without phonological or semantic conflict. None of the measures had higher sensitivity and specificity for individual cases of very mild aphasia compared to letter fluency tasks.
conclusionOur findings suggest that deficits in rapid lexical retrieval and switching with lexical retrieval underlie impaired letter fluency in the NABW group.
