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

The European hoopoe (Upupa epops) conforms a paradigmatic example of animals cultivating bacteria in their uropygial gland that protect them against pathogenic infections. We here explore the hypothesis that enterococci are the responsible bacteria of such beneficial effect. We did so by comparing the antimicrobial activity against three indicator bacteria of colonies isolated from cultures of enterococci and mesophilic bacteria from the uropygial skin or secretion of nestlings, brooding or non-brooding females, and males of the subspecies longirostris in Hainan (China). In accordance with the hypothesis, enterococci isolated from nesting birds are more active than those from non-nesting birds. Moreover, enterococci from the uropygial secretion were more active than those isolated from the skin or than mesophilic bacteria isolates. These results therefore support the hypothesis that, during the nesting phase, hoopoe females and nestlings cultivate enterococci in their uropygial gland with relatively high antimicrobial activity.
