Circovirus infection in Croatian population of Eurasian griffon vultures (Gyps fulvus).
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Circoviruses cause diseases in a wide range of hosts, including avian species. One of the most studied circoviruses is beak and feather disease virus (BFDV), which has spread worldwide due to global trade of birds and characteristics of the virus that allow it to persist in the environment. The Eurasian griffon vulture (Gyps fulvus) is one of the largest birds in the world and is among several vulture species that are considered endangered today, and currently the only remaining vulture species in Croatia. Several juvenile Eurasian griffon vultures undergoing rehabilitation at the Beli Visitor Centre and Rescue Centre for Griffon Vultures on the island of Cres, Croatia, had feather lesions similar to those caused by BFDV in psittacine birds. Signs included partially retained feather sheaths, discoloration and circumferential constrictions of the feather shafts, gnawed feather tips, keratin and egg deposits near the feather shafts, as well as feather breakage and spontaneous feather loss. Feather samples were collected for molecular detection of viral pathogens and macroscopic detection of ectoparasites; blood samples were taken for complete blood count (CBC), biochemical analysis and oxidative stress analysis. The molecular analysis confirmed a circovirus infection, which was supported by the blood analyses indicating a viral infection. The collected ectoparasites were identified as chewing lice - Colpocephalum turbinatum and Falcolipeurus quadripustulatus, which have previously been detected in Eurasian griffon vultures. To our knowledge, this is the first report of circovirus infection in Eurasian griffon vultures. Considering that circoviruses are highly contagious, very resistant and easily transmissible, it is extremely important to perform continuous monitoring in order to improve the breeding and survival conditions of Eurasian griffon vulture populations worldwide.
