However, as the marked decrease in dissipation observed when testing a block at high stress was not easily interpretable in terms of material effects, we questioned the homogeneous fatigue test assumption.
Note: Wilcoxon rank-sum test was not used because box-plots of two AON samples showed that they had different distributional shapes (data not shown), which violated a key Wilcoxon test assumption.
In order to test assumption B', we examined the relationship between k d and k spd at the individual level.
We also compared tabulated mean values of non-EM measured adherence between participants and non-participants/dropouts and tested for differences using the Wilcoxon-Mann-Whitney test (assumption 4).
Either a one-way ANOVA with Dunnett's multiple comparison test (compared with the CTR) or an independent samples t-test with unequal variances (based on Levene's test) assumption was used to analyse the significance of differences.
5 One way to indirectly test Assumption 1 is by exploring whether the distribution of individual or family-level characteristics that are available in the data is the same in different groups defined by the value of the instrument.
