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

backgroundThe increasing interface between human and non-human primate populations in urban centres presents a shared environmental health risk. This risk is particularly prominent at religious sites where close interactions are culturally motivated.

objectivesThis study aimed to determine the prevalence and diversity of gastrointestinal (GI) parasites in free-ranging rhesus macaques (Macaca mulatta) at two UNESCO World Heritage sites in Kathmandu, Nepal.

methodsAn opportunistic, non-invasive cross-sectional study was conducted in July and August 2024. Freshly voided faecal samples (N = 105) were collected from macaques at Pashupatinath Temple (n = 45) and Swayambhunath Stupa (n = 60). The samples were processed using standard coprological techniques, including zinc sulphate flotation and sedimentation, for microscopic examination.

resultsThe overall prevalence of GI parasites was 77.1% (81/105). Nine genera were identified, comprising four protozoans and five helminths, eight of which contain species with recognized zoonotic potential. The most prevalent parasites were Entamoeba sp. (37.1%), Strongyle-type eggs (25.7%), and Strongyloides sp. (20.0%). Double infections were the most frequent pattern (41.0%).

conclusionsThe high burden of potentially zoonotic parasite genera in macaques at these popular international sites highlights substantial environmental contamination and a shared exposure risk at the human-macaque interface. These findings underscore the urgent need for integrated sanitation, public awareness, and management strategies guided by a One Health framework.
