V1-bypassing thalamo-cortical visual circuits in blindsight and developmental dyslexia.
Article in Current opinion in physiology, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
Vision rests on computations that primarily rely on the parvocellular and magnocellular geniculate relay of retinal signals to V1. Secondary pathways involving superior colliculus, koniocellular lateral geniculate nucleus and pulvinar and their V1-bypassing projections to higher order cortex are known to exist. While they may form an evolutionary old visual system, their contribution to perception and visually guided behaviour remain largely obscure. Recent developments in tract tracing and circuit manipulation technologies provide new insights. Here we discuss how secondary visual pathways mediate residual vision (blindsight) after V1 injury by relaying signals directly into higher order cortical areas. We contrast these findings on blindsight with new studies on dyslexia suggesting that dysfunction of secondary visual pathways might contribute to dyslexic's perceptual difficulties. Emerging from these considerations, secondary visual pathways involving koniocellular LGN may be critical for detection of visual change, whereas pulvinar function appears more linked to visuomotor planning.
