  1. Mean changes for nasal lavage biomarkers correspond to differences on logarithmic scale
  2. † Results are from linear mixed models with no interaction. Changes in biomarkers in exhaled air are reported from 5 to 24 h post exposure adjusted for baseline (0 h). For nasal lavage biomarkers no baseline values exist. SP-A and albumin are expressed as weight%. IL-1β and IL-8 are reported in pg/ml. Definition of abbreviations: SP-A = Surfactant Protein-A, IL = interleukin. * The level of significance was assumed at p < 0.05
