Notes: The models include the following serum final values for 25OHD, ucOC, PTH, estradiol, Aβ40 and Aβ42 in Model 1, and is adjusted for demographics (age, education, NART, and BMI) for each cognitive task in the Model 2. n = 42. Values for individual variables are shown only when they reach p < .20 for inclusion in the model, and bolded when p < .09. Aβ = amyloid beta; BMI = body mass index; IED = Intra/Extra-Dimensional Set Shift; NART=National Adult Reading Test; OC = osteocalcin; PTH = parathyroid hormone; RTI = reaction time; SOC = Stockings of Cambridge; ucOC = undercarboxylated OC.
