only marginally significantp = 0.06
When we re-ran the analysis and stratified by smoking status, the difference in VA-FI was only marginally significant in non-smokers ( Z = 1.89, p = 0.06; GW: 0.09 ± 0.09; non-GW: 0.10 ± 0.10) and insignificant in smokers ( Z = 1.04, p = 0.30; GW: 0.19 ± 0.11; non-GW: 0.21 ± 0.12; see Figure 2 ).
