Table 2: Absorbing
events crude cumulative incidence regression model based on pseudovalues. For
each covariate the exponent of regression coefficient is the estimate of the
ratio between crude cumulative incidences. N0 and N1 indicates absence or
presence of axillary lymph node metastases respectively. T is pathological
tumour size (in cm). PgR +,
indicates > 25 or <= 25 femtomoles progesterone
receptors per milligram of cytosolic protein respectively, ER +, indicates
>10 fmoli or <= 10 of estrogen
receptors femtomoles per milligram of cytosolic
protein respectively time and time’ are the spline bases for time.
