To the Editor:

While visualizing the P-value function is desirable, 1 it cannot be done using standard statistical packages. I created a simple EXCEL 2000 spreadsheet to take 2 × 2 contingency table values, compute simple ratios as described in Modern Epidemiology, 2 and graph P-value functions for both the corresponding odds and risk ratios. The spreadsheet can be copied from http://www2.utsouthwestern.edu/publichealth/Aragaki/Epitools.htm, along with documentation. Perhaps it will aid in the instruction of epidemiology students.
