Sleep Data
The sleep data are shown in Table 1. As can be seen in
the table, males and females did not differ on any
polysomnographic measure. Both groups slept reasonably
well, with a total sleep time of 384.5±5.1 minutes (females)
and 364.2±16.8 minutes (males), and sleep efficiencies of
88.7±2.3 % and 86.1±4.1 %, respectively.
