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

A population's dietary niche, including individual variation and specialization, shapes the scope and strength of its trophic linkages. Individual diet variation may emerge in response to spatial variation in the selective pressures that shape trophic morphologies, such as food availability or competition. Therefore, characterizing dietary niche variation and its link to morphological differences among individuals is a key focus in evolutionary ecology. We examined how diet composition and individual specialization varied across space and trophic morphology in threespine stickleback ( Supplementary Information: The online version contains supplementary material available at 10.1007/s10452-026-10299-x.
