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

Households where people have COVID-19 are high-risk environments for companion animals to become infected by SARS-CoV-2. We sampled 579 pets from 281 households with one or more laboratory-confirmed persons with COVID-19 in central Texas from June 2020 to May 2021. Nineteen out of 396 (4.8%) dogs and 21 out of 157 (13.4%) cats were positive for SARS-CoV-2 by RT-qPCR. Additionally, 95/382 (25%) dogs and 52/146 (36%) cats harbored SARS-CoV-2 neutralizing antibodies. Twenty-six companion animals of ten other species were negative. Overall, 164 (29%) pets were positive for SARS-CoV-2 by molecular and/or serological tests; a total of 110 (39%) out of 281 households had at least one animal with active or past SARS-CoV-2 infection. Cats were more likely to be infected by SARS-CoV-2 and had higher endpoint antibody titers than dogs. We detected 11 SARS-CoV-2 lineages and isolated five of them from dogs and cats, including the B.1.234 lineage that was isolated from a cat a few weeks after the first detection in humans in the United States. Detection of SARS-CoV-2 RNA decreased by 10% per additional day post COVID-19 diagnosis of the human case in the household for both dogs and cats, whereas seropositivity odds increased with each additional day. Human-pet interactions associated with a higher risk of infection in dogs and cats included sleeping in the same room as an infected person, living with multiple infected persons, and sharing food with people. The frequency of clinical signs in pets with active infections did not differ from uninfected ones, suggesting that not all reported signs are attributed to SARS-CoV-2 infection. Characterizing animal infections using active SARS-CoV-2 surveillance in pets at risk of infection may aid in One Health pandemic prevention, response, and management.
