Effects Description 
Mean Response Structure* 
(1.1) No group difference 

(1.2) Difference between groups constant across 24hour sequence 

(1.3) Groupspecific mean response functions have different quadratic trends 

(1.4) Groupspecific mean response functions smoothed differently using distinct vectors of coefficients for OSA and Control profiles 

(1.5) Separate smoothing and distinct smoothing parameters for OSA and Control profiles 
Same as structure (1.4) but differing variances for smoothing coefficients: and
