Table 4 Predictors in model for distal radius fracturesa

From: The Amsterdam wrist rules: the multicenter prospective derivation and external validation of a clinical decision rule for the use of radiography in acute wrist trauma

Predictor Coefficient (95 % CI) Odds ratio (95 % CI)
Age (per 10 years) 0.40 (0.25–0.54) 1.04 (1.02–1.06)
Swelling wrist 2.07 (1.44–2.70) 7.92 (4.24–14.8)
Visible deformation 1.38 (0.59–2.17) 3.97 (1.81–8.74)
Distal radius tender to palpation 2.75 (1.22–4.28) 15.7 (3.40–72.4)
Pain on palmar flexion 0.64 (-0.15–1.43) 1.90 (0.86–4.18)
Pain on supination 0.81 (0.15–1.47) 2.25 (1.16–4.37)
Pain on ulnar deviation −0.67 (-1.35–0.02) 0.51 (0.26–1.02)
Pain on radioulnar ballottement test 0.56 (-0.02–1.15) 1.76 (0.98–3.16)
