Efficacy
Statistical methods / analysis
Based on a previously published article (Nieuwdorp et al, J Appl Physiol 2008), the number required to detect a 0.2micrometre difference in the glycocalyx for a significance level of 5% and power of 80% in a paired design (i.e. measuring outcomes before and after an intervention) is n=10. We plan to recruit n=10 in each arm (total 20).
