  1. The effect of trip type (SF = 0, DF = 1) on trip descriptors and ODBA was assessed by linear mixed models including individual identity as a random intercept effect. Marginal (proportion of variance explained by fixed effects) and conditional (proportion of variance explained including both fixed and random effects) R2 were estimated by means of the R package “performance” [44]. Mean values ± SD are reported. Degrees of freedom for the F-tests were estimated according to the Kenward-Roger approximation. Important effects (whose 95% CI do not include zero) are bolded
