Cox proportional-hazards regression analyses for tumour epithelial CB₁IR and pEGFR-IR scores.

Analyses were carried out using data (reported in [16] and [18]) from patients who were followed by expectancy until the appearance of metastases. aTumour stage, bGleason score (in both cases, as well as for pEGFR, the sample sizes used in the univariate analyses are for those which were scored for CB1IR). Exp(B) refers to the increase in the odds as a result of an increase in the “unit” of the predictive variable under study. ***p<0.001, **p<0.01, *p<0.05, NSp>0.1.
