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

Brucellosis remains a critical zoonotic threat to public health and livestock economies globally, particularly constraining small ruminant productivity in Africa, yet continental data remain scarce. The objectives of this review are to provide apparent small ruminant brucellosis prevalence/positivity estimates across Africa by country, region, continent, and diagnostic modality. A systematic search was conducted on PubMed, ScienceDirect, and Google Scholar for articles published from 2000 to 2025. Data from 151 eligible studies representing 28 countries were extracted and meta-analyzed. Due to extreme heterogeneity (
