From: Osteopontin splice variants are differential predictors of breast cancer treatment responses

  Parametric (lognormal) Logrank Wilcoxon
  χ2 p-value χ2 p-value χ2 p-value
exon 4 intensity 4.82 0.0281 9.8692 0.0197 16.3818 0.0009

  1. Quantitative multivariable analysis and non-parametric tests for the prediction of survival by the markers under study (osteopontin-c, exon 4, tumor grade). Used were either the staining levels 0,1,2,3 (intensity) or the combination of 2 and 3 versus 0 and 1 (high/low) under various model assumptions. Underlined p-values are considered significant (p < 0.05)
