INS and type 2 diabetes mellitus: In the multivariate model, living alone (OR 2.48; 95% CI 1.20–5.14; P = 0.015), number of hypoglycemic episodes in the past year (OR 1.06; 95% CI 1.03–1.10; P < 0.001), number of severe hypoglycemic episodes in the past year (OR 2.61; 95% CI 1.20–5.69; P = 0.016), and duration of insulin use (OR 1.06; 95% CI 1.02–1.10; P = 0.006) were associated with FoH in patients with T2D.
