Sleep Heart Health Study

Reliability for SHHS1

Reliability analysis for potential problems according to: large breaths (n=5), arousal problems (n=8), and staging problems (n=5).

2. Arousal problems

The studies (n=8) with potential problems had ICC = 0.43 on the Arousal Index.

Means: 14.80 for 912; 24.47 for 914; and 17.27 for 915.

The studies (n=21) without potential problems had ICC = 0.58 on the Arousal Index.

Means: 13.65 for 912; 19.82 for 914; and 18.15 for 915.
