Acute temporal lesions are associated with phonological word verification errors.

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
Background: Within the dual stream model for language, the bilateral dorsal superior temporal gyrus (STG) is associated with spectro-temporal analysis while the mid-post superior temporal sulcus is associated with processing of higher-level phonological codes. However, the true lateralization of functions needed for phonological discrimination at the word level remains unsettled. The aim of the present work was to determine if individuals with acute stroke primarily involving the left STG and middle temporal gyrus (MTG) demonstrated poorer discrimination ( Methods: One hundred fourteen individuals with acute stroke completed both acute magnetic resonance imaging and a word-picture verification task with phonological and semantic foils. Eighty-nine participants had left hemisphere stroke (51 included the temporal lobe). Twenty participants had right hemisphere stroke (14 included the temporal lobe). Five participants with bilateral stroke were included (3 included the bilateral temporal lobes). Quantile regression was performed controlling for overall lesion volume, age, and sex. Results: While more than half of patients performed the task well, patients with left temporal lobe lesions were more likely to perform poorly. Conclusions: These results confirm a role for the left superior temporal lobe, including the STG, in phonological processing during word recognition, and indicate that a subset of individuals (<50%) have varying degrees of left bias in discrimination of phonologically similar words in the STG.
