Adiponectin, Leptin, and Resistin in Asthma: Basic Mechanisms through Population Studies

Figure 3

Nonlinear relationship between serum adiponectin and risk of incident asthma in a US-based longitudinal study [69]. The depicted relationship may show a threshold effect that is only seen with the lowest tertile of serum adiponectin concentration. The symbol * represents a significant ( ) comparison with respect to the high tertile. In another US-based cross-sectional study, a similar threshold effect was seen between the highest quartile of serum leptin concentration and prevalent asthma in women [66].
