Gastrointestinal parasites of endemic and endangered free-ranging purple-faced leaf monkey (Semnopithecus vetulus) in Sri Lanka: effect of host group size and habitat type.

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.
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
Similar infectious agents may be shared among human and nonhuman primates due to their close proximity. Gastrointestinal parasitism is one of the main diseases which can be transmitted between human and nonhuman primates. It is vital to understand the potential transmissions of gastrointestinal parasites (GIP) and monitor their prevalence in free-ranging populations. This study was carried out to determine the prevalence and diversity of the GIP of Semnopithecus vetulus in Sri Lanka from December 2017 to April 2019. Fresh fecal samples (N = 78) were collected and analyzed using fecal floatation technique and direct iodine mounts. Of these, 55% contained at least one species of GIP (helminths: N = 18 protozoans: N = 30). Multiple infections were recorded in 12% of the samples testing positive for parasites. The most prevalent helminth was Trichuris trichiura (15%). A significant relationship was found between the prevalence of T. trichiura and troop size. There were also significant differences in the prevalence of T. trichiura and Ascaris lumbricoides with habitat type. Compared to the forest dwelling populations sampled, those dwelling in urban and suburban habitats receive higher solar radiation, daytime temperatures and disturbance from humans. These conditions can be expected to influence GIP infection rates. S. vetulus living in continuously degrading habitats face a significant threat from GIP infections. Continuous and improved parasitological surveillance is needed to help monitor the conservation status of wildlife and to secure human health.
