Bootstrapping was conducted with B = 10.000 samples. A BCa 99.8% CI_B (corresponding to p < 0.002) was used to correct for multiple comparisons. Partial correlations control for eBAC and are significant if the BCa 99.8% CI_B does not contain zero, indicated by *. Abbreviations: r_P = partial correlation, r_PB = bootstrapped partial correlation, eBAC = estimated blood alcohol concentration, SE = standard error, BCa = bias-corrected and accelerated, CI_B = bootstrapped confidence interval.
