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

Research on assortative mating has shown that couples share strong similarities in demographic and attitudinal variables, while the similarity in personality is generally weak. However, a recent meta-analysis indicated that couple similarity in dark traits is considerably greater than that in the Big Five. If these differential similarities are primarily due to active preference, we expect that (1) the desire for similarity in dark traits should be higher than that for the Big Five and (2) the strongest desire for partner similarity in dark traits should come from the "darkest" individuals (i.e., with the darkest core).
