  1. Values are rates (95% confidence interval), expressed as number of events per 1000 patient-years. Rates are crude or standardized for sex, age by the direct method. Comparison of event rates among groups was done by log-rank test.
  2. Choosing dippers as reference group, and comparing the 2 other groups (non-dipper, reverse-dipper) to this group throughout. *Indicated comparison with the dippers P < 0.025.
