LEP and asthma: In asthmatics, BMI adjusted leptin correlated positively with asthma symptom score (rho = 0.371, p = 0.031) and negatively with lung volumes VC% predicted (rho = -0.445, p = 0.007), FVC% predicted (rho = -0.406, p = 0.016, Figure 3) and with FEV1% predicted (rho = -0.345, p = 0.045, Figure 4), i.e. the higher the leptin level, the poorer the lung function and the more symptoms.
