Table 1 Multivariable models with general shape: Pain after compression = Σ Effect × Predictor value

From: Pain-preventing strategies in mammography: an observational study of simultaneously recorded pain and breast mechanics throughout the entire breast compression cycle

  Model 1 (n = 281) Model 2 (n = 324)
Predictor Effect Significance Effect Significance
Recollected pain score [NRS] 0.763 p < .001 excluded  
Baseline pain score [NRS] 0.108 p = .06 0.263 p < .002
Maximum reached force [daN]    −0.204 p < .005
Duration of clamp phase [sec] −0.046 p = .10 −0.075 p < .05
  1. Model selection was performed by stepwise minimization of the Akaike Information Criterion. Model 1 includes the recollected pain scores of the previous mammogram (available for n = 281 cases). In model 2 (all cases: n = 324), the recollected pain scores were excluded.
