  • The analyses are performed per protocol and as ITT.

  • *Hypertension if no hypertension at baseline, hypercholesterolaemia if no hypercholesterolaemia at baseline, COPD if no COPD at baseline, diabetes if no diabetes at baseline, hypothyroidism if no hypothyroidism at baseline, hyperthyroidism if no hyperthyroidism at baseline or depression if no depression at baseline.

  • †Too few in each group to report for ethical reasons.

  • COPD, chronic obstructive pulmonary disease; ITT, intention to treat.
