Appendix Figure. Markov states in screening for colorectal cancer (CRC) by fecal occult blood test (FOBT) (top), flexible sigmoidoscopy (middle), and colonoscopy (bottom). The black and gray ovals represent Markov states in which patients remain for at least a full 1-year cycle. The white ovals represent intermediate states of screening procedures, which patients may enter and leave during one cycle. The arrows represent transitions between various states.
