Figure 4.
Effect of CPAP treatment on circulating FABP4 (circles) and FABP5 (squares) levels in OSA patients. CPAP, continuous positive airway pressure; FABP4, adipocyte fatty acid-binding protein; FABP5, epidermal fatty acid-binding protein; OSA, obstructive sleep apnea. The results represent mean and the SD for FABP4 levels or the median and 25th-75th percentiles for FABP5 levels. The FABP4 values were adjusted for age, gender, BMI, and insulin levels. *P < 0.001.
