highly significantP ≤0.001
For instance, as is shown in Table 1 , the two-way rANO-VAs with repeated measure “Time” and independent factor “Strain” always yielded a highly significant main effect of factor “Strain,” as well as a highly significant main effect of interaction between this factor and “Time” (eg, P ≤0.001 for sleep measure in any of these rANOVAs).
