HbA1c glycated haemoglobin; SD standard deviation; SDM-Q-9 shared decision making (9 items scored 0–5, total score is the sum 0–45, more SDM with higher score); PACIC patient assessment of chronic illness care (11 items scored 1–5, score is the mean 1–5, better care with higher score); PAID problem areas in diabetes (20 items scored 0–4, total score is the sum multiplied by 1.25 = 0-100, more distress with higher score); EQ-5D-3 L quality of life (5 items with 3 levels, total score is the weighted EQ-5D index from low negative values to 1.0, better QoL with higher score)
