 Our work, inspired by [Ordovas et al. (2023)](https://doi.org/10.1016/j.cmpb.2023.107405), aimed to replicate their BN-based CVD risk prediction using a different dataset. Additionally, we sought to explore the broader potential of BNs in CVD risk assessment, conducting in-depth analyses beyond the original paper.
