Table 3 Results of lung function and hyperreactivity testing at T0 and T1

From: Diisocyanate-induced asthma in Switzerland: long-term course and patients’ self-assessment after a 12-year follow-up

  T0 T1 p-value
FVC% predicted 102 ± 17 96 ± 17 0.04
FEV1% predicted 91 ± 16 87 ± 18 0.06
FEV1/FVC 76 ± 9 73 ± 8 0.01
PD20 (mg) 0.95 (1.7) 0.70 (1.7) 0.81
  1. Legend: FVC = forced vital capacity. FEV1 = forced expiratory volume in one second. PD20 = provocative dose of methacholine causing a 20% fall in FEV1. NSBHR = nonspecific bronchial hyperreactivity.
  2. Data is presented as mean ± SD or median and interquartile range (IQR).
