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

Predation risk for depleted prey populations is known to be influenced by prey abundance. However, predation risk may also be influenced by the abundance of sympatric prey species, particularly when the sympatric species is abundant. This suggests that predation risk estimates for low-abundance prey may also need to account for the abundance of sympatric species. To understand how sympatry between two prey species with differing abundances affects predation risk, we used an unstudied system in arid Southern California where the co-occurrence of federally Endangered Peninsular bighorn sheep (
