Towards personalized intensive care decision support using a Bayesian network: A multicenter glycemic control study

Personalized treatment in glycemic control (GC) is a visibly promising research area that requires improved mechanisms providing patient-specific procedures to enable complicated decision support. Available per-patient data must be more than written records, and be fully integrated in this personali...
