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

Understanding the temporal dynamics of predator-prey interactions is the basis for predicting behavioral responses to climate or other environmental changes. Bats, as generalist apex predators, can provide a holistic view on ecosystem health, because their diet integrates signals from diverse insect communities and rapidly reflects environmental change. However, most molecular diet studies lack the temporal resolution needed to infer hunting strategies and prey choice mechanisms, because guano-derived species lists cannot be meaningfully interpreted without knowing when and what potential prey were available. Previous research has typically analyzed eDNA metarcoding data or insect activity patterns separately, limiting insights into mechanisms underlying prey selection. This study combines eDNA metabarcoding of bat guano with metabarcoding of time-stamped insect samples collected using automated Malaise traps to investigate the foraging ecology of long-eared bats (
