Signature of the Risk Profile of Mortality in a Hospital Cohort of Patients With Metabolic Diseases
Epidemiological studies are usually conducted in the general population in adults without complications or pathology at baseline. The results obtained are therefore often better designed for primary prevention use. The prediction of mortality risk in patients with complications and requiring hospital follow-up is less well known. The study purpose is …
