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

Consider the classic Ebbinghaus illusion in figure 1: the orange circle on the right seems bigger, even though both orange circles have the same size. Such size illusions occur in the real world too: in fact, a common dieting trick is to serve the same food on a smaller plate, which makes it appear larger, so you end up eating less. Why do we get fooled by such size illusions?
