Description and molecular characterization of novel Leucocytozoon parasite (Apicomplexa: Haemosporida: Leucocytozoidae), Leucocytozoon polynuclearis n. sp. found in North American woodpeckers.
Article in Systematic parasitology, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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.
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
We describe Leucocytozoon polynuclearis n. sp. (Haemosporida: Leucocytozoidae) from two North American woodpeckers, the northern flicker (Colaptes auratus Linnaeus) and white-headed woodpecker (Dryobates albolarvatus Boie, 1826), based on the morphology of its blood stages and portions of the mitochondrial cytochrome b gene. The most distinctive features of Leucocytozoon polynuclearis n. sp. development are the triangular-shaped host cell nuclei and position of host cell nuclei above gametocytes. This parasite inhabits thrombocytes. Leucocytozoon squamatus Nandi, 1986, the only other Leucocytozoon species detected from Picidae birds, lacks features that are commonly found with L. polynuclearis n. sp. infections. Phylogenetic analysis identified DNA lineages associated with L. polynuclearis n. sp. and showed that this parasite is more closely related to other North American Leucocytozoon species than to L. squamatus, whose initial description was from infected Old World Picidae species. Although there are reports of L. squamatus in North American Picidae species, these detections were based only on microscopic examinations, remain genetically non-characterized, and might be misidentifications with regards to L. polynuclearis n. sp. Available parasite distribution data indicate that L. polynuclearis n. sp. infects Picidae species throughout North America and L. squamatus distribution probably is restricted to Old World Piciformes birds.
