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

Long-tailed macaques (Macaca fascicularis) are bred in China for export and for use in experiments. Entamoeba infections in captive long-tailed macaques were surveyed in one of the biggest colonies located in Guangxi Province, China. One stool sample was obtained from each of the 152 different cages representing >3,000 macaques in the colony. The samples were examined by PCR for five Entamoeba species. The number of detected Entamoeba coli infections comprised 94% of the samples, 93% for Entamoeba chattoni, and 83% for Entamoeba dispar. In contrast, Entamoeba histolytica and Entamoeba nuttalli were not detected. Six isolates of E. dispar were obtained by culture in Tanabe-Chiba medium. Analysis of serine-rich protein genes in these isolates showed two genotypes, one of which is identical to that of the E. dispar SAW760 strain in humans. This suggests transmission of E. dispar between humans and nonhuman primates. These results demonstrate that Entamoeba infections are common, but virulent Entamoeba species are absent in this colony. This work also confirms the need for monitoring with PCR-based identification of Entamoeba species for captive macaques in breeding colonies to ensure animal health and protection of humans from zoonotic hazards.
