Note: (1) Figures are hazard ratios from the parametric Weibull regression. Hazard ratios are based on models controlling for age, urban-rural residence, ethnicity,
education, lifetime primary occupation, economic independence, current marital status, co-residence with children, currently smoking, alcohol consumption at present,
and doing regular exercise. (2) Panels A and B are from conventional regressions where both SSA and OSA are two independent variables and are simultaneously
included in the regressions. Results in Panels C, D, and E are from the same regression with a different category as the reference, while Panel F is from a different
regression where the first three categories are pooled together. (3) +p<0.1, *p<0.05, **p<0.01, ***p<0.001.
