The frequency distribution of genetic risk score (GRS) and the coefficient and 95% <i>CI</i> to genetic risk score in linear regression model adjusted for height, age and FEV₁ at baseline, and average log transformed endotoxin level.

<p>The more risk loci the subjects carried, the larger the rate of FEV₁ decline occurred (<i>P</i>_trend = 3.01×10⁻¹⁸).
