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

Although hemoplasma infection has been widely described in animals, a few studies have been conducted involving human populations, mostly as case reports. This was a cross-sectional epidemiological study that accessed hemoplasma infection in individuals and dogs from ten Indigenous communities of southern and southeastern Brazil. A total of 23/644 (3.6%) individuals of ten Indigenous communities tested positive to hemoplasmas by quantitative polymerase chain reaction (qPCR) (cycle threshold; Ct ≤ 34.4), with 3/644 (0.5%) Mycoplasma haemocanis detection. In addition, 91/416 (21.9%) dogs were positive to hemoplasmas by qPCR, with 54/91 (59.3%) for M. haemocanis, 27/91 (29.7%) for Candidatus Mycoplasma haematoparvum, and 10/91 (11.0%) for both. Molecular diagnosis of M. haemocanis in Indigenous people herein may be consequence of daily close contact with dogs and different potential vectors. Although apparently healthy individuals, hemoplasma infection should be considered as differential diagnosis in likely overexposed populations, such as Indigenous individuals.
