  • Mann-Whitney U test was used for comparisons of age and 25-OH vitamin D3. Fisher's exact test was used for all other comparisons.

  • *‘other disease’ includes hypertension, body pain, hypothyroidism and gastritis as most common diagnoses.

  • BE, bronchiectasis; COPD, chronic obstructive pulmonary disease; CVID, common variable immuno deficiency; ND, increased susceptibility to infections without a defined immunological disorder.
