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

Species of Hepatozoon are parasites frequently recorded in snakes. The species identification of this genus was based mostly on the gametocyte morphology and morphometric calculations. For more reliable results, molecular characterization, an initial step for the correct identification of Hepatozoon species, has been used. This study aimed to determine the prevalence and identification of Hepatozoon species in captive snakes from Brazil. To that end, morphological, morphometric, and molecular data were obtained. A total of 157 snakes; 128 venomous (Crotalus durissus) and 29 non-venomous (Epicrates crassus and Boa constrictor) were screened for Hepatozoon blood parasites. Using light microscopy, 20 (12.78%) snakes were found positive for Hepatozoon spp., of which 6/29 (20.7%) were non-venomous and 14/128 (10.9%) were venomous; all with low parasitemia. Polymerase chain reaction (PCR), performed with the primers HepF300/Hep900, confirmed all 20 (100%) samples positive for hemogregarines. Species of Hepatozoon were identified from eight sequenced samples. Two previously described species, Hepatozoon cuestensis and Hepatozoon musa, were identified. The present study is the first to report H. musa within the snake hosts E. crassus and C. durrisus. In addition, a potentially new Hepatozoon species from B. constrictor was identified.
