    A physical examination was used to screen for breast cancer in 2,500 women with biopsy-proven adenocarcinoma of the breast and in 5,000 age- and race-matched control women. The results of the physical examination were positive in 1,800 cases and in 800 control women, all of whom showed no evidence of cancer at biopsy.

    The sensitivity of the physical examination was 72.0%, Specificity of the physical examination was 84.0%, and the positive predictive value of the physical examination was 69.2%.

    Problem with setting up all the above data sensitivity, specificity and positive predictive values in one table and show formulas for sensitivity, specificity & positive. I have a difficult time with placing data in the example question and utilizing a table. Thanks.
