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

Island systems provide valuable natural laboratories for investigating how ecological constraints drive physiological evolution. Although dietary shifts are known to influence morphological divergence in insular lizards, their consequences for digestive physiology remain insufficiently understood. Using 10 wild populations of the Skyros wall lizard (Podarcis gaigeae) across the Skyros Archipelago, we tested whether fine-scale variation in habitat and prey availability predicts divergence in digestive performance. We quantified arthropod abundance, gastrointestinal morphology, gut passage time, digestive enzyme activity and apparent digestive efficiency (ADE) under standardized laboratory conditions. Islet populations consistently exhibited slower gut passage, longer gastrointestinal tracts, higher protease and lipase activities, and greater ADE relative to populations on the main island of Skyros, indicating enhanced digestive performance in resource-limited environments.
