Reduced Systemic Levels of IL-10 Are Associated with the Severity of Obstructive Sleep Apnea and Insulin Resistance in Morbidly Obese Humans

Table 3

Correlation between circulating levels of IL-10 and polysomnographic characteristics of the study subjects.

	IL-10	value
Total sleep time (hours)	0.24	NS
Sleep latency (min)	−0.53	0.0092
Sleep efficiency (%)	0.19	NS
Light sleep (%)	−0.38	0.033
Slow wave sleep (%)	0.14	NS
REM sleep (%)	0.49	0.0083
Mean SaO2	0.18	NS
Total arousal index	−0.6	0.0065
AHI	−0.64	<0.0001

Coefficient and values were calculated by the Spearman’s correlation model. The correlation level was considered significant when . AHI, apnea-hypopnea index.
