Mortality risk, aka "risk of dying," still at 100% for everyone. Many people care about reducing the risk of dying in the next X months or years, but saying that walking or anything else reduces that risks assumes knowing how long that person would have lived in the control group. Since that proves impossible, this study compares similar individuals, some of whom walked and some of whom didn't, or walked less.
