  1. OR Odds ratio; ROM Range of motion; CAM Complementary and alternative medicine
  2. Only statistically significant variables from univariate regression were included using stepwise method in multivariable logistic regression with age and gender (p < 0.05)
  3. aAny self-reported gastritis, tuberculosis, poliomyelitis, cardiovascular disease, uterine myoma, or hepatitis B carrier
  4. bRegarded no ROM restriction if (a) cervical flexion > 30o at admission, (b) cervical extension > 30o at admission, (c) left cervical rotation angle = right cervical rotation angle at admission, and (d) left cervical side-bending angle = right cervical side-bending angle at admission were all satisfied. Regarded ROM restriction if any of the above-mentioned conditions were not met
  5. cRegarded positive physical exam result if any exam of (a) compression test, (b) distraction test, (c) Valsalva test, (d) Spurling test was positive at admission. Regarded negative physical exam result if all exams were negative. If any exam was uncheckable due to pain or functional disability, it was considered to be a positive test result
