Table 2.

Linear regression analysis for physiological extinction recall (dERI; N=67). Sex, %REM, REMD and REML were significant predictors. Note that smaller dERI denotes better extinction recall. %REM: Proportion of REM sleep to the total sleep time; REMD: REM density; REMF: REM fragmentation; REML: REM latency.
