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 aim of the present study was to verify the occurrence of hemogregarines in the colubrid snake Thamnodynastes lanei from the eastern Amazon region of Brazil. Intraerythrocytic gamonts with mean dimensions of 14.8 ± 1.8 × 4.0 ± 0.7 μm and encapsulated gamonts with mean dimensions of 15.3 ± 1.1 × 4.8 ± 0.5 μm were observed. Through morphological and molecular data based on the partial 18S rDNA gene, the parasite was identified as Hepatozoon cevapii, originally described in the viperid snake Crotalus durissus terrificus from the southeast region of Brazil. Thus, the findings of the present study extend the geographic range of H. cevapii and provide novel Hepatozoon-snake associations.
