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

The study of partner resemblance has widespread implications in the social and natural sciences. To date, the vast majority of such research has focused on opposite-sex couples. This study compared patterns of partner correlations ("assortment") across 66 traits in the UK Biobank (UKB) in 89,628 female-male (FM), 236 female-female (FF), and 216 male-male (MM) putative couples. The average FF, MM, and FM correlations were positive (indicating similarity rather than dissimilarity), though both same-sex partner types yielded significant correlations for only a minority of traits at the Bonferroni-corrected level. FM pairs showed more positive assortment (p
