  1. *Frequency of exacerbation data (available for 61 patients). Frequent exacerbators defined as >3 episodes per annum. + Indicates treatment within the last month with antibiotics other than maintenance colomycin or azithromycin. Values followed by different letters are significantly different (p < 0.05). When corrected for sex and height the FEV1% predicted were similar between the 2 genders.
