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

Does crossing one's path result in greater uncertainty in one's internal sense of direction (path integration)? The present study addressed this issue using immersive virtual reality involving matched paths with and without a crossover. Crossed compared to uncrossed paths showed greater pointing variability to the start location; the location of the crossover also had an effect on pointing variability. A simple vector addition model was not able to capture these results, suggesting the need for additional assumptions. These findings suggest that a looped crossover path incurs more errors in path integration, suggesting important constraints on models of path integration.
