Domestic cat hepadnavirus genotype B is present in Southern Brazil.
Article in Virus genes, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Domestic cat hepadnavirus (DCH) (Orthohepadnavirus felisdomestici) is an emerging virus related to the hepatitis B virus (HBV) already reported in many countries. The molecular prevalence of DCH varies widely in the regions investigated so far. In the present work, we reported the presence of DCH in Brazil. Sixty cat serum samples tested by DCH presence using PCR and 1.67% (1/60) were positive, similar to the low positive molecular rates reported in United States and Japan. The DCH full-length genome was classified in genotype B, which is uncommon since this genotype was only reported once in Japan. The DCH-positive sample was obtained in a stray cat female apparently healthy, presenting ALT, AST, and ALKP normal values, and negative for FIV and FeLV. Due the low positivity rate detected, some factors as alteration in hepatic enzymes and FIV/FeLV infection could not be evaluated. Other works are necessary to statistically validate these observations in Brazil.
