1 · What the graph read from it

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.

2 · The registry

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

Pseudoneglect, considered the archetype of spatial attentional asymmetries among neurologically healthy individuals, is traditionally described as a consistent leftward error in visuo-spatial tasks. Here we challenge this notion by revealing a consistent rightward "internal" bias in a task where participants' representational encoding of visuo-spatial information is captured. Our meta-analysis across seven experiments in 1750 neurotypical individuals robustly demonstrates a rightward internal bias in the expectations of objects in space. Moreover, we show that this bias is malleable, with a simple behavioural intervention that manipulates prior expectations, albeit with limited generalisability. By successfully recalibrating a spatial bias, our research highlights the potential for cognitive adjustments in addressing spatial cognition challenges such as those in unilateral spatial neglect after stroke.
