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

Hepatozoon species are the most widely known haemogregarines infecting a wide range of vertebrates, although predominately snakes. Herein, Hepatozoon bashtari n. sp., originally infecting the painted saw-scaled viper, Echis coloratus, in Saudi Arabia is described using both morphological features and molecular data from 18S rDNA sequences. The overall prevalence of infection was 60% (9/15) with parasitaemia ranging from 52 to 60%. Gamonts were entirely intraerythrocytic and were observed to cause considerable hypertrophy within the host cell. The mean size of mature gamonts was 15.4 × 3.3 μm. Merogonic stages were confined to the lung endothelial cells with monomorphic meronts. The average size of mature meronts was 32 × 12 μm and they were estimated to produce 13-16 merozoites each. The phylogenetic tree generated from SSU rDNA sequences revealed that Hepatozoon bashtari sp. n. clusters with the vast majority of other Hepatozoon species infecting snakes, lizards and geckos in various regions of the world, which would appear to support the hypothesis of prey-predator transmission of the genus Hepatozoon. Through a combination of morphological comparison with closely related Hepatozoon spp. and 18S rRNA gene sequence analysis, it is possible to confirm Hepatozoon bashtari sp. n. as a new species.
