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

purposeNumber magnitude is often represented spatially in the mind by a mental number line, on which small numbers are located to the left of space and large numbers to the right. As vestibular dysfunction can affect aspects of spatial cognition, we wondered whether patients with acute vestibular loss would show a directional bias along the mental number line.

methodsWe gave 18 patients with vestibular neuritis (VN) (eight left VN, ten right; mean age 54 years, range 31-75 years; four females) and 15 normal age- and education-matched controls (mean age 47 years, range 26-75 years; 11 females) a mental number bisection task.

resultsThe patients with left VN underestimated the middle number (mean sum of signed errors -3.3, SE 1.5), while patients with right VN overestimated it (mean 1.9, SE 0.7). The direction of effect aligned with the direction of slow phase velocity. The results for the normal controls fell in between the two patient groups, and represented an underestimate of the middle number (mean -1.5, SE 0.8). In the patients, the effect was greater without visual fixation and in the acute stage compared to 1 or 2 weeks later. The error rates were similar across all groups and conditions.

conclusionsOur results show that acute vestibular loss produces a temporary directional bias in numerical processing that is only present in the absence of visual cues. The effect is similar to that seen in patients with visuospatial neglect.
