The Stroop Effect in Aphasia: A Narrative Literature Review.
Review in Advances in experimental medicine and biology, 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
Aphasia is a language-specific disorder that crosses modalities and is linked to impairments of the cognitive mechanisms used to build and use linguistic representations. The color-word Stroop task (C-WST) is frequently used to investigate cognitive deficits. This review examines its use in people with aphasia (PWA).
objectiveTo explore the extant literature using C-WST to determine select cognitive deficits in PWA.
methodFour online database searches were conducted using "Stroop" and "aphasia" keywords. Eight studies were identified following examination of a second set of criteria: (1) presence of aphasia, (2) use of the C-WST, and (3) RT and accuracy measurement of incongruent and control (neutral or congruent) conditions for determining interference and facilitation effects within and between PWA and healthy controls (HC).
resultsSix studies meeting criteria employed relatively small groups, and two examined a single PWA. Studies examined bilingual language dominance, age, aphasia classification, and cognitive mechanisms of aphasia. RT interference effects were reported for PWA in all studies and in six of the eight HC groups. Facilitation effects were infrequently reported. Over-additive PWA interference effects were reported in five of the eight studies.
conclusionOverall results show an interference effect on the C-WST for both PWA and HC groups and an over-additive interference effect for PWA. The paucity of C-WST search results for PWA meeting criteria is too few to draw conclusions supporting a direct link between an inhibition impairment and the aphasic language deficit. Findings support a need for further research in PWA using the C-WST.
