Fig. 5: Example Bayesian Network (BN) for modelling tisk of developing background myocarditis based on age and sex.
From: A Bayesian network analysis of the Pfizer COVID-19 vaccine in the paediatric population

The output node “Background myocarditis over three months”, linked (via arrows) to two parent nodes “Age” and “Sex”. The model assumes 33% 5–11 year-olds, 34% 12–15 year olds and 33% 16–17 years old, with 50% male and 50% female.
