Abstract
I read with interest the paper by Alberto-Orlando et al [[1]Alberto-Orlando S Calderon JL Leon-Sosa A et al.SARS-CoV-2 transmission from infected owner to household dogs and cats is associated with food sharing.Int J Infect Dis. 2022; 122: 295-299https://doi.org/10.1016/j.ijid.2022.05.049Abstract Full Text Full Text PDF PubMed Scopus (15) Google Scholar] entitled “SARS-CoV-2 transmission from infected owner to household dogs and cats is associated with food sharing”. Investigation of human-animal transmission and factors associated with that is an important area of study. The authors report interesting prevalence data, but also an association between food sharing and SARS-CoV-2 infection in pets. That risk factor would be biologically plausible; however, the data and analysis are unclear and do not appear to support that conclusion. Description of the analysis is very superficial and provides little information about the methods. For multivariable analysis, the authors report a significant association between food sharing and infection (P = 0.0025) with an odds ratio of 6.17. Yet, the reported 95% confidence interval (0.22-167.4) is very broad and is inconsistent with a statistically significant result. The bivariate analysis for this variable yielded a P-value of 0.61, and it is surprising that such a change could result from multivariable analysis, especially with such a small sample size and a limited number of variables. This raises the question of whether there was an analysis error as it is very difficult to see how a significant result such as this could be obtained. The author has no competing interests to declare. Concerns regarding risk factors for SARS-CoV-2 transmission to pets: author's replyInternational Journal of Infectious DiseasesVol. 130PreviewWe read with interest the letter by S. Weese entitled "Concerns regarding risk factors for SARS-CoV-2 transmission to pets: Alberto-Orlando et al. 2022" [1]. In this letter, concerns were raised regarding our recent publication “SARS-CoV-2 transmission from infected owner to household dogs and cats is associated with food sharing” [2]. We appreciate the critical reading of our manuscript and we are addressing the concerns in this letter. Full-Text PDF Open Access

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
