Morphological and molecular characterization of avian trypanosomes in raptors from Thailand.

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
From September 2012 to May 2018, blood samples from 364 raptors (mostly adults) were collected and screened for trypanosomes and haemosporidians by microscopic examination and nested polymerase chain reactions (PCR). Trypanosoma spp. were identified in 15 birds from eight different species. Light microscopy revealed 14 cases of infection with Trypanosoma cf. corvi, including one each in black-shouldered kite (Elanus caeruleus, n = 49), Brahminy kite (Haliastur indus, n = 50), and spotted owlet (SO, Athene brama, n = 27); two mountain hawk-eagles (Spizaetus nipalensis, n = 3); and three each in Asian barred owlets (ABO, Glaucidium cuculoides, n = 27), barn owls (BO, Tyto alba, n = 65) and collared scops owls (CSO, Otus lettia, n = 41). In addition, one case of infection with T. avium was identified in an oriental scops owl (OSO, Otus sunia, n = 2). All infected raptors showed very low parasitemia levels. The PCR detected more three positives in one CSO, one Japanese sparrowhawk (Accipiter gularis), and one OSO. The sensitivity and specificity of the PCR method were 93.3% and 99.1%, respectively. The overall infection rate was very low (4.9%). The highest infection rate was recorded in cold-dry season (9.9%). Coinfection of Plasmodium with trypanosomes was found in all three ABOs. Coinfection with Haemoproteus spp. was found in one BO, three CSOs, and one SO. Coinfection with Haemoproteus spp. and Leucocytozoon danilewskyi was found in the OSO. Microfilarias were detected in one ABO and one CSO. The ultrastructure of trypomastigotes of T. cf. corvi in an ABO revealed fine structures. All small subunit ribosomal RNA (SSU rRNA) sequences belong to two clades: T. avium and T. corvi-culicavium complex/group. SSU rRNA gene amplification was not successful in one BO. The raptors with trypanosome infections showed normal hematological values and healthy appearance. Furthermore, this is the first report of T. avium in a nocturnal raptor from Thailand.
