Fig. 4From: The value of high-resolution computed tomography (HRCT) to determine exercise ventilatory inefficiency and dynamic hyperinflation in adult patients with cystic fibrosisScatterplots between V’E/V’CO2 slope, Δ IC and V’E/V’CO2 intercept. Continuous and dash lines represent fit line and 95% CI, respectively. Vertical lines in the above scatterplots represent the defined cut-off of V’E/V’CO2 slope and Δ IC (30 and − 100 L, respectively)Back to article page
