A reseаrch teаm set оut tо determine the diаgnоstic accuracy of a physical examination to screen for breast cancer. Results of the physical exam were compared to a gold standard of the presence of biopsy-proven adenocarcinoma of the breast. The physical examination was used to screen for breast cancer in 3,000 women with biopsy-proven adenocarcinoma of the breast (the gold standard) and in 6,000 age- and race-matched control women (without biopsy-proven adenocarcinoma of the breast). The results of the physical examination were positive (i.e., a mass was palpated) in 1,800 women with biopsy-proven adenocarcinoma of the breast and in 800 control women who showed no evidence of cancer at biopsy. What was the positive predictive value of the physical examination? Give your answer as a percentage. (Hint: construct a two by two table to help you complete this calculation.)
