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

Blood samples from 72 Ameiva ameiva lizards from Central Amazonian upland forests were collected, and thin smears of 40 (55.5%) animals were positive for gamonts of Hepatozoon with a mean level of intensity of infection of 14 parasites/2000 blood erythrocytes (0.73%). The gametocytes were found attached with host cells' nuclei, and their dimensions were 14.28 ± 1.05 μm in length and 4.50 ± 0.80 μm in width. Phylogenetic analyses of the 18S rRNA gene showed that the new sequences obtained from A. ameiva constitute a monophyletic sister clade to the Hepatozoon spp. from Brazilian snakes. Based on morphological features and new molecular data, we redescribe this hemogregarine as Hepatozoon ameivae. This study also provides the first molecular characterization of a Hepatozoon species from a Brazilian lizard.
