Of note, the mediation model of thalamus activation mediating the relationship between length of NREM 2&3 sleep and PVT median speed was marginally significant (indirect effect estimate=059, p = 0.067); and the significant path c in this model (Table S5 ) suggested a negative direct effect without introducing the mediator (estimate = −0.008, p = 0.03).
