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

The study of the structure of ectoparasite communities in wild mammals is fundamental, as it contributes to comprehend the ecological and health dynamics of these systems. This study analyzed the structure of ectoparasite communities in wild carnivores and rodents in central Chihuahua, Mexico, considering biological variables of the hosts (species and sex) and environmental factors such as temperature in one year cycle. A total of 745 ectoparasites were collected, including 738 fleas (seven species, two families), four lice (two species), and one tick species. Seasonal variation and host family significantly influenced the presence and frequency of ectoparasites. Flea species clustered by host group: Pulicidae predominated in carnivores, with Pulex simulans being the most abundant species during winter, while Ceratophyllidae dominated in rodents, with Malaraeus eremicus as the most abundant flea in autumn-winter and Jellisonia sp. nva. in spring-summer. No significant interspecific interactions were observed among flea species. In rodents, no significant relationship was found between the rodent’s sex and the presence of fleas. In northern Mexico, studies on the composition and interactions of ectoparasite communities in wild mammals and their seasonal structuring are scarce. This research provides new records of ectoparasite-host interactions in the state of Chihuahua, Mexico, and updates current knowledge on how biological and climatic factors influence ectoparasite community behavior. These findings offer valuable insights for biology, public health, and species conservation.
