Notes: Mean (and standard error) of objective (actigraphic) and subjective (diary) sleep parameters of the two conditions (regular sleep, partial sleep deprivation). t-Test analysis results (t and p) are also shown.
Abbreviations: TST, total sleep time; EFF, sleep efficiency; WASO, wake after sleep onset; S-TST, subjective total sleep time; S-WASO, subjective wake after sleep onset.
