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

Arboreal primates rely heavily on acoustic communication, making them ideal candidates for passive acoustic monitoring (PAM). Here, we investigated the detectability of vocalisations from Alouatta belzebul, Callithrix jacchus, Saimiri spp, and Sapajus flavius in three fragments of Atlantic Forest and two fragments of Caatinga Forest in northeastern Brazil. We recorded each area for 48 h per month over 7 months, placing one audiomoth recorder at each site. Our results show that all species were detectable through PAM, with varying detection rates: 8/13 known call types for C. jacchus, 14/31 for S. flavius, 2/4 for A. belzebul, and 6/27 for Saimiri spp. Not all calls from their vocal repertoire were detected. Call detectability was influenced by species, habitat, time of day, and month. We emphasise the importance of considering behavioural, dietary, and home-range patterns when designing PAM protocols for primates. Our findings provide valuable insights for optimising PAM studies and highlight the need for continued basic research on vocal repertoire descriptions to improve conservation efforts.
