Associations of quartiles of accelerometer-derived sleep midpoint (n = 38,701) on adjusted odds of type 2 diabetes in employed UK Biobank participants of European descent

Sleep midpoint	Type 2 diabetes case/control subjects, n/n	Sex- and age- adjusted OR (95% CI)	Sex-, age-, and household status–adjusted OR (95% CI)
Quartile 1	168/9,508	Reference	Reference
Quartile 2	104/9,571	0.64 (0.55–0.75)	0.65 (0.56–0.77)
Quartile 3	120/9,555	0.72 (0.61–0.86)	0.75 (0.63–0.89)
Quartile 4	163/9,512	0.95 (0.77–1.17)	0.96 (0.78–1.19)

Prevalent type 2 diabetes associations are sex- and age-adjusted ORs (95% CI). Boldface type indicates P < 0.05. In sensitivity analysis, associations were further adjusted for people residing in the household with the participant (household status).
