  1. All continuous variables were first z-transformed.
  2. BMI = Body Mass Index; CCI = Charlson Comorbidity Index; CI = Confidence Interval; MMSE = Mini-Mental State Examination; OR = Odds Ratio; OWD = Occiput-to-Wall Distance.
  3. aAdjusted for vertebral fractures, the Cobb angle, the OWD, and the number of prescriptions. After step 1, the OWD was excluded.
