  1. TM and OM refer to measurements obtained by the tonometric SphygmoCor technique at the radial artery or by the oscillometric Mobil-O-Graph monitor (1000–2000 hours) at the brachial artery, respectively. Values are mean±s.d. The number of measurements averaged per subjects were 2 for TM and 4 for OM in the R study and 2 for TM and ⩾10 for OM in the R+A study (Figure 1).
  2. Significance of the sex difference: *P<0.05, †P<0.01 and ‡P<0.001.
