RT Journal Article SR Electronic T1 Insulin therapy for the non-specialist physician JF Clinical Medicine JO Clin Med FD Royal College of Physicians SP e323 OP e326 DO 10.7861/clinmed.2021-0266 VO 21 IS 4 A1 Svetla Stefanova YR 2021 UL http://www.rcpjournals.org/content/21/4/e323.abstract AB Insulin is required for all people living with type 1 diabetes, and may be required in nearly half of those with type 2 diabetes.
