INS and type 2 diabetes mellitus: Guidelines commonly recommend an individualised glycated haemoglobin (HbA1c) goal with a default target of <53 mmol/mol (<7.0%) for most insulin-requiring individuals with type 2 diabetes (T2D) [9,10], though more stringent goals (<48 mmol/mol; <6.5%) are recommended for some (younger patients with minimal comorbidities) and less stringent goals (~64 mmol/mol; ~8.0%) for others (elderly patients or those with hypoglycaemic unawareness) [9].
