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 purpose of this study was to perform a phylogenetic analysis of Hepatozoon spp. infecting Philodryas patagoniensis in Uruguay. Twenty-five road-killed specimens of P. patagoniensis from ten departments were obtained. Samples of blood and/or heart tissue were taken. Polymerase chain reaction (PCR) assay was carried out amplifying a specific target region of the 18S rRNA gene of Hepatozoon spp. Eighteen out of twenty-five samples were positive to Hepatozoon spp., which gave an overall prevalence of 72%. Phylogenetic analyses with the obtained sequences were carried out to determine the relationship with closely related species found in the region. The results revealed that samples were split into two clades with a high bootstrap support. Clade I was formed with Hepatozoon spp. sequences obtained in this study from P. patagoniensis, Hepatozoon cuestensis from Crotalus durissus terrificus and Hepatozoon musa from Philodryas nattereri, and Hepatozoon spp. retrieved from Cerdocyon thous, Hemidactylus mabouia, and Phyllopezus pollicaris from Brazil, respectively. Clade II was grouped with Hepatozoon cevapii and Hepatozoon massardii, both species described for C. d. terrificus from Brazil. This is the first report of Hepatozoon spp. in snakes from Uruguay.
