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

In contrast to their terrestrial call, the offshore call of penguins during their foraging trips has been poorly studied due to the inaccessibility of the foraging site-the open ocean-to researchers. Here, we present the first description of the vocal behaviour of penguins in the open ocean and discuss the function of their vocal communication. We deployed an animal-borne camera on gentoo penguins (Pygoscelis papua) and recorded their foraging behaviour during chick guarding. From the video recordings, we collected 598 offshore calls from 10 individuals in two breeding seasons (2014-2015 and 2015-2016), and we analysed the acoustic characteristics and behavioural contexts of these calls, including diving patterns, group association events, and foraging behaviour. The offshore calls varied in their dominant frequency and length, and penguins produced calls of different lengths in succession. Group associations were observed within one minute following an offshore call in almost half of the instances (43.18%). Penguins undertook dives of shallower depths and shorter durations after producing an offshore call than those before producing an offshore call. Our findings show that penguins may use vocal communication in the ocean related with group association during foraging trips.
