Survival and adherence to cpap in the elderly

multiple regression analysis. The correlation between stress before the start of the study and PSG data was not significant, but the correlation to the mean stress ratings during the 6 weeks was significant (r = .50). Conclusion: It was concluded that moderately increased stress over a longer period of time is related to moderate signs of disturbed sleep during that period but that habitual stress ratings are not.
