Thank you for warm message, @krfeeney
I admit that the post I’ve written is somewhat confusing.
Actually, what I meant was a kind of simple PLP model for CV death, which is externally usable.
For example, if the patient has myocardial infarction during short-term period before death, and does not have any history of malignancy or other life-threatening condition, we can assume that his/her mortality was caused by cardiovascular disease (It would be more definite if he/she had a history of ECMO during short-term period before death).
