Preserved motion perception and the density of cortical projections to V5 in homonymous hemianopia.
Article in Brain communications, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Following a unilateral post-chiasmal lesion of the geniculo-striate pathway, patients develop homonymous visual field defects. Using classical perimetry, patients with 'complete' homonymous hemianopia are unaware of stimuli in the affected hemifield. However, some show preserved vision in the affected hemifield in which the conscious perception of moving stimuli is preserved (Riddoch phenomenon). Prior evidence suggests that preservation of a direct pathway from the lateral geniculate nucleus to visual area 5 (bypassing the primary visual cortex) may be the basis of this type of residual vision. The aim of the present study was to investigate the possibility of a correlation between preserved motion perception in hemianopia and the fibre connectivity density of the underlying pathways. This research was a case-control study carried out in a tertiary care centre between 2019 and 2021. Participants (
