Ancient origins and global spread of domestic cat hepatitis B virus.

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
Mammalian hepadnaviruses have likely been evolving alongside their hosts for millions of years. Domestic cat HBV (DCHBV) has been detected in cats from several countries, but its genealogy, epidemiology, and host range remain unclear. Besides DCHBV, the only hepadnavirus identified among carnivores is the ringtail HBV (RtHBV). Because there is a gap in the felid fossil record of approximately 5-7 million years between the late Oligocene and the early Miocene, carnivore-derived viruses might help to shed light on Felidae evolution. Here, we screened 2260 sera and 154 paraffin-embedded liver samples from cats and 2123 sera from dogs sampled in Europe and South and Central America between 2018 and 2020 by PCR for DCHBV. We identified DCHBV genotype A (GtA) in 0.6% (7/1,195; 95% CI, 0.2-1.2) of cats sampled in Germany, France, Croatia, and Bulgaria and a genetically divergent DCHBV genotype B (GtB; 10.8% genomic sequence distance) in 0.2% of cats (2/1,065; 95% CI, 0.0-0.7) from Brazil. The detection rates of the two genotypes did not differ significantly (Fisher,
