using stepwise variable selection , the mean nuclear cytoplasmic ratio ( normal , mean 20.4 ( s.d . +/- 2.0 ) ; tumour , mean 39.7 ( s.d . +/- 7.0 ) ) and the coefficient of variation of nucleus to cell apex distance ( normal , mean 19.2 ( s.d . +/- 7.5 ) ; tumour , mean 47.8 ( s.d . +/- 9.1 ) ) were chosen as discriminating features .
