Neuroanatomical correlates of phonologic errors in logopenic progressive aphasia.
Article in Brain and language, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 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
While phonologic errors may be one of the salient features of the logopenic variant of primary progressive aphasia (lvPPA), sparse data are available on their neuroimaging correlates. The purpose of this study was to identify brain regions associated with different types of phonologic errors across several tasks for participants with lvPPA. Correlational analyses between phonologic errors across tasks most likely to elicit such errors and specific left hemisphere gray matter volume regions were conducted for 20 participants. Findings point to the inferior parietal lobe and supramarginal gyrus as being the most relevant correlates. Atrophy in these regions may increase the likelihood of making phonologic errors in lvPPA, particularly substitution error types. Our results provide support for neuroanatomical correlates of phonologic errors in the parietal region, which is consistent with previous findings of temporoparietal cortex involvement/atrophy in lvPPA.
