  1. Data are expressed as median (interquartile range) or number (percentage). We obtained information on gait speed from questionnaires during health check-ups. If a study participant answered “YES” to the following question: “Do you walk faster than others of the same age and sex?” then this study participant was categorized as having fast gait speed. If a study participant answered “NO” to this question, then this study participant was categorized as having slow gait speed.
