Adjusted associations in a generalized additive model. Regression splines representing the adjusted associations in a generalized additive model between the 6-minute walk distance (6MWD) and (a) variation of heart rate (ΔHR) during the test, (b) initial heart rate (HR) at the beginning of the test and (c) C-reactive protein (CRP) levels. y axis corresponds to variation of 6MWD as a function of the explanatory variables. Dashed lines correspond to 95% CI of the spline
