| Abstract: | The contents of 16 trace elements(TE) in 90 urinary samples collected from the high, medial and low incidence of esophageal cancinoma(EC) districts (Shantou area)were variance and multivariable stepwise discriminant analysed by computer.The stepwise discriminant equations were established by 8 variables. Applying the discriminant equation to the high,medial and low incidence.districts by resubstitution test 83.3% accuracy and to the other 114 samples accuracy is 76.3% Thus,these equations may provide a basis for prediction high,madial and low incidence of Esophageal cancer. |
