(b) IGFBP2 levels were not significantly different () comparing people with OSA ( ng/ml) and control ( ng/ml). (c) Levels of IGFBP3 are comparable between people with OSA ( ng/ml) and control ( ng/ml). (d) Circulating IGFBP4 was significantly higher () in people with OSA ( ng/ml) compared to control ( ng/ml).
