Figure 3From: Sleep apnea predicts distinct alterations in glucose homeostasis and biomarkers in obese adults with normal and impaired glucose metabolismBiomarker profiles associated with OSA in normal vs. impaired glucose metabolism. Figure 3A presents the correlations of LowSaO2 and ΔSaO2 with TNF-α level (solid diamond) in the control group of 15 women with normal glucose metabolism. Figure 3B displays the correlations of LowSaO2 and ΔSaO2 with IL-6 level (solid circle) and the correlations of IL-6 with BMI (solid square) and leptin-to-leptin receptor ratio (solid triangle) in the case group of 15 women with impaired glucose metabolism. The fitted curve represents a linear regression fit between the two variables. r = Pearson product-moment correlation coefficient; rho = Spearman's rank correlation coefficient.Back to article page
