INS and gestational diabetes: Further analyses, which included only patients who developed GDM, revealed that insulin sensitivity (OR = 0.83, 95% CI 0.74‐0.92, P < .001 for the increase of 1 unit of QUICKI × 102) and β‐cell function at early gestation (OR = 0.93, 95% CI 0.89‐0.97, P = .003 for the increase of 1 unit of DI × 102) were inversely associated with the requirement of pharmacotherapy.
