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

purposeCystic echinococcosis (CE) is a cosmopolitan parasitic zoonosis with public health and economic significance. In this study, we report CE in uncommon host, a chimpanzee (Pan troglodytes) in the Kuwait Zoo with description of clinical and pathological findings.

methodsIn September 2025, a 32-year-old adult female common chimpanzee (Pan troglodytes) died at the zoo of Kuwait after showing severe symptoms. Post-mortem examination revealed a handball-sized cyst embedded in the hepatic umbilical fissure, causing lesions. The content of the cyst was examined microscopically as well as by sequencing of the mitochondrial nad1 gene from one of the clonal protoscoleces found in the cyst.

resultsThe cyst proved to be Echinococcus granulosus sensu stricto, genotype G1. The clinical case of the infection is described in detail. DNA sequence was nearly identical to sequences of G1 genotype of E. granulosus available in GenBank.

conclusionsThis report of CE in a chimpanzee in the zoo highlights the problem related to environmental contamination. The implication of dogs in environmental contamination and other aspects of CE epidemiology in Kuwait is discussed. This is the first report of genetically identified hydatid cyst of E. granulosus sensu stricto in Kuwait and the first genetically confirmed case of the genotype G1 in chimpanzee.
