Table summary
This table displays the results of results of sleep duration trajectory model. The information is grouped by parameters (appearing as row headers), high-normal sleepers, short sleepers, low-normal sleepers and long sleepers, calculated using estimate and standard error units of measure (appearing as column headers).
