In our recent diabetes study which looked at the effect of mixed nuts on blood sugar control (REB# 06-274), 44.8 % (35/78) of participants continued onto follow-up and 24% (19/78) completed follow-up. All crossed from either the muffin (control) or half dose nut supplement to the full dose nut (test) supplement. In a recent Portfolio study (REB#04-056), after 24 weeks 62.5% of participants crossed from DASH diet (control) to Portfolio diet (test). Assuming that in this study participants will also cross from the control diet to the test diet, we will use a paired t-test with no adjustment for baseline or sequence, as this is not a true crossover design.
