INS and type 2 diabetes mellitus: A study in 83 people with type 2 diabetes and depression, showed that BLT reduced depressive symptoms (−3.9 [95% CI −9.0, 1.2] Inventory of Depressive Symptomatology points) and improved insulin sensitivity (0.15 mg/kg × min [95% CI −0.41, 0.70] measured using hyperinsulinaemic–euglycaemic clamp), although neither change was statistically significant [70].
