marginally significantp = 0.047
For the metric of modularity, the effect of scan length on the interaction between threshold and age group showed that there was a marginally significant interaction between age group and threshold for participants who completed the longer rest scan ( F 24 , 2248 = 1.534, p = 0.047), but there was a strong, significant interaction between age group and threshold for those who completed the shorter rest scan ( F 24 , 1088 = 2.734, p < 0.001).
