- Means for the diabetes example of Senn et al. [7] were computed from model (2), dropping the design × treatment interaction (G.T) and modelling heterogeneity (G.S.T) as random. Pairwise comparisons at a family-wise Type I error rate of 5% by Edwards-Berry [20] test. Means with a common letter are not significantly different. The letter display was obtained by the method of Piepho [21]. Treatments are sorted in ascending order of means for ease of interpretation.
