A comprehensive review of Onchocercidae nematodes (Nematoda; Filarioidea) infecting wild ruminant ungulates of North and Central America.

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
The family Onchocercidae, or filarioid nematodes, comprises common vector-borne parasitic worms that can infect, among other vertebrates, wild North American ruminant ungulates. Infection is a product of the available hosts and vectors distributed in viable ecosystems that permeate throughout the North America (i.e., Canada, United States, and Mexico) and Central America (i.e., Belize, Costa Rica, El Salvador, Guatemala, Honduras, Nicaragua, and Panama). The formation of these host-parasite assemblages can produce serious to no apparent clinical signs for the infected host animal depending on a multitude of factors. Overall, the scope of our knowledge regarding filarioid nematode infection of North American wild ruminant ungulates remains spotty and neglected throughout the scientific literature. However, reviewing these details provides a foundation for important biological, historical, ecological, and one health relevant questions. Analysis of the current scientific literature reveals that, at this time, nine out of fourteen wild North American ruminant ungulates can be infected with at least one species of filarioid worm. This includes four genera of known Onchocercidae species circulating within the North and Central American ecosystems:
