Table 3 Predictors in model for all 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) 0.35 (0.22–0.49) 1.04 (1.02–1.05)
Sex (if male) 0.38 (–0.10–0.86) 1.46 (0.90–2.35)
Swelling wrist 1.48 (1.00–1.96) 4.40 (2.72–7.11)
Swelling anatomical snuffbox 0.47 (-0.08–1.02) 1.60 (0.92–2.78)
Visible deformation 1.32 (0.54–2.09) 3.73 (1.72–8.11)
Distal radius tender to palpation 0.88 (0.23–1.53) 2.41 (1.25–4.63)
Pain with radial deviation 0.67 (0.08–1.26) 1.95 (1.08–3.51)
Pain with axial compression of the thumb −0.37 (-0.88–0.14) 0.69 (0.41–1.15)
  1. The coefficient of each dichotomous variable reflects the amount of change in the log odds of a fracture. The coefficient of the continuous variable age reflects the amount of change in the log odds of a fracture for every ten-year increase in age
