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

Understanding parasite epidemiology is essential for managing endoparasite infections in free-ranging animals. However, such epidemiological knowledge is limited for feral cattle and is usually derived from farmed populations. We assessed endoparasite infection in a feral cattle population in Hong Kong. This population does not receive any routine care or anthelminthic treatment, although some cattle are provisioned with water and hay by local citizens. We assessed three indices of endoparasite infection (parasite richness, prevalence and fecal egg/oocyst count) and their associated risk factors (season, provisioning, marshland access, group size, sex and body condition) in adult cattle. We conducted sedimentation, McMaster and coproculture techniques on 262 samples collected from 177 cattle. We identified eleven taxa of nematodes, two taxa of trematodes, one taxon of protozoan and one taxon of cestode. Median parasite richness was two parasite taxa per individual. Trematode infections were the most prevalent (91.22 %), followed by protozoan (67.17 %), nematode (23.22 %) and cestode (12.97 %) infections. Counts averaged 144.85 oocysts per gram for
