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

Diurnal raptors in the order Accipitriformes are commonly parasitized with Leucocytozoon spp., and the prevalence and intensity of parasitemia are often high. However, for raptors in Falconiformes, several studies have reported relatively low prevalences (1 % or less) of Leucocytozoon spp. Leucocytozoon parasite pathogenicity has been documented in falcons, but little is known about the diversity, prevalence, and phylogenetic relationships among Leucocytozoon species in these predatory birds. The research reported here combines molecular and microscopic techniques to identify and describe Leucocytozoon parasites in Falco sparverius sparverius, the American kestrel, and place those parasites into a phylogenetic context with leucocytozoids previously found in other diurnal raptors (Accipitriformes), owls (Strigiformes), passerines (Passeriformes), and other bird species. Of 35 American kestrels sampled, 13 birds (37.1 %) were found by PCR to harbor the DNA lineage of a novel species, Leucocytozoon californicus. No other Leucocytozoon parasite lineages were identified in our sample. Phylogenetic analysis revealed that this parasite clusters more closely with leucocytozoids found in owls and passerines than it does with leucocytozoids found in birds of the genera Buteo and Accipiter of the order Accipitriformes. This is the first described species of Leucocytozoon that parasitizes diurnal raptors in which gametocytes develop exclusively in roundish host blood cells. It is also the first Leucocytozoon species that is described and named in birds of the Falconiformes, in which, for unclear reasons, leucocytozoids are significantly less prevalent and less diverse than in raptors with a similar behavioral ecology belonging to the Accipitriformes.
