Statistical methods / analysis
A sample size of 16 has 80% power, alpha 5%, to detect a difference of 0.75 standard deviations, and a sample size of 32 of about 0.5 standard deviations, for continuous variables. A sample size of 16 (in each group) gives good precision for estimation of variance.
Our experience is that periostin and Fractional exhaled Nitric Oxide (FeNO) have highly skew distributions and are likely to need analysis on the logarithm transformed scale. The main analysis will be by paired t-tests. For variables needing a logarithm transformation this is interpreted as the ratio of means when back –transformed. A linear mixed model will be used to compare the difference between the paired measurements by normal and asthma groups.
