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

Introduction Haemoproteus spp. (Haemosporida: Haemoproteidae) are widespread avian blood parasites known for their high genetic diversity and host specificity. Haemoproteus spp. can cause internal organ damage to their vertebrate hosts, which raises concerns about their health impacts. However, the distribution of Haemoproteus spp. in Africa, particularly among non-passerine birds, remains poorly understood, with unknown implications for species conservation. Sub-Saharan Africa, including The Gambia, hosts several critically endangered vulture species, including Hooded Vultures (Necrosyrtes monachus), yet information on their haemosporidian parasites is scarce. This study aimed to identify an effective primer set for detecting Haemoproteus parasites in Hooded Vultures and to provide the first molecular confirmation of infection in this species and country. MethodsBetween 2019 and 2025, Hooded Vultures were blood sampled in The Gambia, and microscope slides were screened for parasites. Samples microscopically positive for Haemoproteus spp. were subjected to DNA extraction and polymerase chain reaction (PCR) analysis using different primer sets targeting the mitochondrial cytochrome b (cytb) gene. ResultOf these, only UNIVF/ UNIVR3 amplified Haemoproteus spp. DNA from the Hooded Vulture samples. Sequencing and phylogenetic analyses revealed a novel Haemoproteus lineage, named hNECMON01. This represents the first molecular record of avian haemosporidian parasites in Hooded Vultures and in The Gambia. ConclusionOur findings highlight the importance of optimizing molecular tools for detecting haemosporidian parasites in non-passerine hosts and contribute to our understanding of the diversity of Haemoproteus spp. in sub-Saharan Africa. Further studies on parasite diversity in scavenging birds are essential for integrating parasite monitoring into avian conservation efforts.
