Table 2 Odds Ratios (unadjusted and adjusted) for complex (AO type B and C) vs. less complex (AO type A) distal radius fractures

From: No association between osteoporosis and AO classification of distal radius fractures: an observational study of 289 patients

  OR with 95% CI
Exposures Unadjusted Adjusted
BMI 1.0 (0.8–1.3) 1.0 (0.7–1.3)
Current smokinga 0.4 (0.2–0.9) 0.4 (0.2–0.8)
Previous smokinga 0.8 (0.4–1.3) 0.7 (0.4–1.3)

  1. OR Odds ratio, CI Confidence interval, BMI Body mass index
  2. Relevant risk factors adjusted for were: age, sex, BMI, smoking, bone mineral density and low energy trauma
  3. aReference category was the non-smoking group. When analyzing current smoking, the group of previous smoking is removed, and vice versa
  4. bReference category was no osteoporosis (osteopenia and normal bone mineral density)
  5. cReference category was normal bone mineral density (T-score ≥ − 1.0)
  6. dReference category was age < 65
  7. eReference category was female sex
  8. fReference category was no low energy trauma
