  1. HR, hazard ratio; CI, confidence interval. The data are presented as the hazard ratio (95% confidence interval [CI]). In adjusted model the results of physical fitness tests and motor ability tests (low, medium, high), age (continuous variable), body mass index (low, medium, high) and daily step counts at the follow-up survey were entered as adjusted factors
  2. a Step-test scored using the index derived from the formula shown in the eMaterials
