Red-tailed monkeys (Cercopithecus ascanius) prey upon and mob birds in the Issa Valley, western Tanzania.

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.
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
Interactions between monkeys and birds are rarely observed and, consequently, rarely described in the scientific literature. We recorded two encounters between birds (Prionops plumatus and Strix woodfordii) and red-tailed monkeys (Cercopithecus ascanius) in a woodland-mosaic habitat in western Tanzania. We observed a male red-tailed monkey consume a small bird in its entirety. Although only a few feathers remained, we provisionally identified the bird as a white-crested helmetshrike. We also observed a group of red-tailed monkeys mobbing, but not killing, an African wood owl on the forest floor. This is the first reported observation of this kind. These encounters suggest that guenons may generalize large-bodied avians as threats and small-bodied avians as potential prey. Hetero-specific encounters such as these provide insights into primate diet and anti-predatory behavior.
