Data are presented as r, unless otherwise stated. Bold type represents p<0.05. T/B: target/background; ACE: angiotensin-converting enzyme; sIL-2R: soluble interleukin-2 receptor; BAL: bronchoalveolar lavage; VC: vital capacity; FEV₁: forced expiratory volume in 1 s; D_LCO: diffusing capacity of the lung for carbon monoxide. ^#: ACE insertion-/deletion-corrected ACE activity; ^¶: FEV₁/forced vital capacity×100; ⁺: statistically significant after Bonferroni correction.
