Molecular and Morphological Analyses of Leucocytozoon Parasites (Haemosporida: Leucocytozoidae) in Raptors From Thailand.
Article in Acta parasitologica, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 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
introductionLeucocytozoon spp. causes a vector-borne disease that is nonpathogenic in domestic and wild birds. To date, there was no report of leucocytozoonosis in raptors from Thailand.
methodsThis study was carried out to perform morphological and molecular analyses of Leucocytozoon in 400 raptors at a rehabilitation center at Kasetsart University, Thailand during a 7-year period. The nested PCR was used to amplify the cytochrome b gene of Leucocytozoon with primers HaemNF1 and HaemNR3 as the primary reaction.
resultsThe light microscopic examination revealed Leucocytozoon gametocytes in five raptors; three diurnal raptors [two Crested Goshawks (CGs, Accipiter trivirgatus) and one Eastern Imperial Eagle (EIE, Aquila heliaca)], and two nocturnal raptors (one Oriental Scops-Owl (OSO, Otus sunia,) and one Short-eared Owl, Asio flammeus) and two species were identified: Leucocytozoon danilewskyi in both owl species and L. californicus in two CGs. The PCR method revealed more infection rate (2.0%, 8/400) than the light microscopic method including one Barred Eagle-Owl (BEO, Bubo sumatranus), one Brown Hawk Owl (BHO, Ninox scutulata) and one OSO. A phylogeny revealed that sequences from one SEO and one OSO were clustered with L. danilewskyi and the three Leucocytozoon sequences from diurnal raptors were clustered with L. californicus. The other three sequences from a BHO, a BEO and an OSO were ambiguous.
conclusionThis study combined morphological, morphometric and molecular phylogenetic analyses to identify L. danilewskyi in two species of owls, L. californicus in three diurnal raptors, and unknown species in three other owls, representing the first records of leucocytozoon infection in raptors from Thailand.
