Statistical analyses
The sample size estimation was based on the two treatments for which the smallest difference was expected (D40 and CON). Given this was a crossover trial, it was expected that the other comparisons (with D20-P) would have sufficient power. No ɑ corrections were made to account for the multiple comparisons. Furthermore, it was assumed that the within-person correlation for the response measures on the different treatments was 0.65. We aimed at finding a significant decrease in time below range with at least 20% increase in time in range during the night after the exercise test and 50% increase in next-morning fasting glucose concentration [
