Word Picture Verification Performance Reveals Auditory Comprehension Deficits in Primary Progressive Aphasia.
Article in Journal of neurolinguistics, 2023. 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
Word/picture verification has been found to be a sensitive measure of lexical-semantic abilities in post-stroke aphasia and reveals information about disruptions in semantic and phonological processing. Exploration of the nature of auditory comprehension deficits using word/picture verification has not been replicated in primary progressive aphasia (PPA). We tested 108 individuals with PPA [logopenic variant PPA (lvPPA), n = 50; nonfluent agrammatic PPA (nfaPPA), n = 36; semantic variant PPA (svPPA), n = 22] on a spoken word/picture verification task and a spoken word/picture matching task. The spoken word/picture matching task identified 22 (20%) of individuals as impaired, whereas the spoken word/picture verification task identified 51 (47%) of individuals as impaired (two-tailed p < 0.001). Errors on spoken word/picture verification were due to semantic rather than phonologic foils in lvPPA (nouns, p < 0.001; verbs, p < 0.001), svPPA (nouns, p < 0.001; verbs, p < 0.001), and for nouns (p = 0.001) but not verbs in nfaPPA. Spoken word/picture verification was a more sensitive measure of single-word auditory comprehension deficits in PPA than word/picture matching. The error pattern, consistent with the distributed model of semantic knowledge, suggests that degradation of semantic representations for both nouns and verbs can occur in lvPPA, which may help to distinguish lvPPA versus nfaPPA and guide treatment for anomia.
