E. Blinded 31. You are tasked with analyzing the negative predictive value of an experimental biomarker for ovarian cancer. You elect to enroll 2000 patients across multiple clinical sites, including 1000 patients with ovarian cancer and 1000 age-matched controls. From the disease and control subgroups, 700 and 100 are found positive for this new for this test? biomarker, respectively. Which of the following represents the NPV A. 900/(900+ 100) B. 700/(300+900) C. 900/(900+300) D. 700/(700+100) E. 700/(700+300) misad double.blind.controlled trial is conducted on the efficacy of 2 different ACE-inhibitors.
