Optimizing Detection of Very Mild Aphasia With Letter Fluency Tests.
Article in American journal of speech-language pathology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
purposeThe purpose of this study was to find an efficient measure for clinicians to diagnose very mild aphasia.
methodTwenty-seven individuals with very mild aphasia who tested as not aphasic by the Western Aphasia Battery-Revised (WAB-R; NABW) were compared to 68 matched controls on 28 tests. Group-level differences were determined with independent-samples
resultsTwenty out of 28 behavioral tests and subtests had group-level differences, with 18 surviving Bonferroni correction. Only scores derived from letter fluency and a two-letter fluency test had sensitivity and specificity ≥ .70. The Boolean combination of letter fluency and two-letter fluency tests gave a sensitivity of .89 and specificity of .81.
conclusionsThe combined letter fluency and two-letter fluency tests were sensitive in detecting very mild aphasia beyond what is captured in the WAB-R. Administration takes an estimated 11 min, making it accessible to clinicians in various settings. While letter fluency tests rely on phonological and orthographic knowledge, they are also frequently used to measure executive control. Thus, this combined letter fluency test should be used in conjunction with other language and cognitive assessments to determine treatment targets.
