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

Roads can form barriers to movement and act as mortality sinks for bats. However, understanding flight behaviour over roads has been limited by reliance on human observers to characterise flight patterns. Moreover, both species-specific behaviour and the local environment may alter bat-road interactions. Using paired near-infrared cameras with 3-D tracking analysis, we reconstructed the flight trajectories of barbastelle bats (Barbastella barbastellus) at nine road sites in West Sussex, England. Of the 400 flight paths, 56% occurred at heights that placed bats at risk of vehicle collision, and this risk increased as bats flew closer to canopy cover. Increasing canopy cover was associated with bats flying along rather than across roads, and with faster flight speeds (by 0.14 ms
