Immediate improvement: comparison of first 3 MST trials in morning to final 3 from night (1A). Plateau improvement: measured by comparing final 6 MST trials in the morning with final 6 trials at night (1B). OSA subjects showed significantly less overnight improvement on the MST for both measures.

Correlation Overnight MST Improvement by Age.
There was a significant negative correlation between overnight MST improvement and age for the OSA group (2A: r2 = 0.3; p = 0.01), an effect that was not observed in the Non-OSA group (2B: r2 = 0.08; p = 0.23).
