CI = confidence interval; HBV = hepatitis B virus; OR = odd ratio; n/N = number of practitioners with a low knowledge score/total number of practitioners for a specific category.

^*Practitioners that attended at least one lecture or other didactic event dedicated to HBV infection aside their initial medical training.

^†In your medical practice, do you propose the screening of HBV infection to your patients?

^‡In case of a pediatric patient, would you usually check his/her HBV vaccination status?
