Table 5 Factors associated with being in the advanced VAT group rather than the stable VAT group via multivariable logistic regression analysis.

βOdds ratio95% CIP value
AIC: 29.391. Delta index represents the index of exercise test with a mask minus the corresponding index of exercise test without a mask. VAT – ventilatory anaerobic threshold; CI – confidence interval; VE – ventilation per minute; BF – breath frequency; VE/VCO – carbon dioxide ventilation equivalent.
