Fig. 2. Modified standard gamble table showing percentage risk of developing and not developing cancer.
The research interviewer started at step 1 by asking the participant if she would elect the risk management strategy under evaluation if she had a 0% risk of endometrial or colorectal cancer. If the participant answered NO, then the interviewer moved to step 2 and asked the same question. This process continued until the participant answered YES to the electing the management strategy described in a given health state.
1 Colorectal cancer was the target cancer of interest when for any health state that involved colonoscopy; endometrial cancer was the target cancer of interest for health states that involved HYST/BSO, transvaginal ultrasound, and CA125, as well as the chemoprevention health state. Both cancers were considered with combined screening health states.
