H131 variant is associated with impaired pulmonary function at baseline. (A) FEV1 (forced expiratory volume in 1 second), (B) FVC (forced vital capacity), and (C) DL _CO (diffusing capacity of the lung for carbon monoxide) were determined in IPF patients and their association with FcγRIIa R131H genotypes was assessed. Data are presented as the mean percent predicted value ± 95% confidence intervals (CI). *p < 0.05 RR vs. HH, **p < 0.01 RR vs. HH.
