Variable | Est. Diff. LS Means | (SE) | p-value2 | Est. Diff. LS Means | (SE) | p-value2 | Est. Diff. LS Means | (SE) | p-value2 |
Airway Area (mm2)) | −93.3 | 31.9 | 0.007 | −58.3 | 29.9 | 0.06 | 13.9 | 29.9 | 0.64 |

LAT Diameter (mm) | −3.6 | 1.7 | 0.04 | −2.5 | 1.6 | 0.12 | 1.6 | 1.6 | 0.33 |
Notes: Overall differences among conditions were significant for airway area [F(3,30)=5.1, p=0.006], anteroposterior (AP) diameter [F(3,30)=5.5, p=0.004], and lateral (LAT) diameter [F(3,30)=4.1, p=0.015], respectively.
p-values reflect statistical significance of linear contrasts relative to wakefulness.
