Statistical methods / analysis
60 Participants will be recruited to the study. Assuming at most 20% withdrawal/exclusion rates during the study this will ensure complete data on at least 50 participants. An achieved sample size of 50 has reasonable precision for estimates of variance.

Statistical analysis: The baseline characteristics of the population will be described and the variance and mean values for serum periostin will be calculated for participants who complete the study without developing a severe exacerbation. Confidence intervals for the variance of periostin will be calculated using a Chi-square statistic. This analysis may need to be performed on the log transformed scale.
