Table 4 Predictive value of symptoms for T-stage of anal carcinoma. The final model of our multivariate logistic regression analysis had significant predictive value to distinguish a localized vs. locally advanced tumor (R 2 = 0.37; p = 0.03). In the table the odds ratio (OR) of a symptom or physical finding for prediction of locally advanced cancer (T3/T4 vs. T1/T2) are shown. Only variables with p < 0.100 are indicated
