  1. Estimated average changes in ΔPNIF and ΔPEF (L min−1) during each exposure scenario (estimated mean) and differences between the two HVO exposures and FA exposure (beta). The beta values (L min−1) and significance (p value) are based on the linear mixed model with exposure order correction. Values within brackets are the 95% CI
