Mediation of the associations between WASO and fragmentation and odor identification by cognition in NSHAP Wave 2 olfaction-sleep subsample

Beta Coefficient 95% CI p-value
WASO
 A: Association with cognition −0.034 (−0.056, −0.012) <0.01
 B: Association of cognition with Odor ID (adjusting for WASO) 0.063 (−0.006, 0.131) 0.07
 Indirect association of WASO with Odor ID through cognition −0.002 (−0.005, 0.001) 0.14
 Direct association of WASO on Odor ID (not mediated through cognition) 0.011 (−0.020, −0.002) 0.01
Fragmentation
 A: Association with cognition −0.083 (−0.152, −0.015) 0.02
 B: Association of cognition with Odor ID (adjusting for fragmentation) 0.073 (0.007, 0.140) 0.03
 Indirect association of Fragmentation with Odor ID through cognition −0.006 (−0.012, 0.003) 0.22
 Direct association of Fragmentation on Odor ID (not mediated through cognition) −0.033 (−0.014, 0.002) 0.15
