Data are for veterinary students who attended a fetotomy exercise at the University of Copenhagen, Denmark, from September 2018 to June 2019, and completed the questionnaire (n = 97).

AR, attack rate; RR, risk ratio; CI, confidence interval; NA, not applicable; PPE, personal protective equipment.

Those who replied “I don’t know/I don’t remember” were omitted from the analysis for the specific determinant.
