Information was available in ≥97% of participants, except that education level was missing in 7% of the 2380 participants, and HADS-D was missing in 14% of the 5297 invitees and 11% of the 2380 participants. HbA1c, fasting and 2-hour oral glucose tolerance test s-glucose, and education level were measured/queried only in the 2380 participants.
