HLA-DRB1 and latent autoimmune diabetes in adults: The frequencies of DRB1*03 (OR = 2.685, 95% CI: 2.060–3.501, pc< 0.013), DRB1*04 (OR = 1.954, 95% CI 1.507–2.535, pc < 0.013), and DRB1*09 (OR = 1.334, 95% CI: 1.141–1.559, pc < 0.013) were significantly higher in patients with LADA than in the controls, which suggests that all three are risk factors for LADA.
