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 IUCN-Endangered kipunji (Rungwecebus kipunji) is one of Africa's rarest primates, restricted to two isolated populations in Tanzania. The Udzungwa population is enigmatic, confined to a small area within a large, old-growth forest and consists of fewer than 100 individuals. Apart from baseline data from 2006, ecological knowledge remains scant. We present new data from three standardized sweep censuses conducted between 2013 and 2024 in Ndundulu forest along 42-45 linear transects of 2 km in length. Per census, only 4 to 6 kipunji groups were recorded, within a range of 10.42 km
