a The coefficient (β) reflects the magnitude (in hours) of the effect on the pre-hospital timespan associated with the variable’s presence (in the case of the dichotomous variables MPI poor and male sex) or of each unit of the continuous variables, distance to hospital (in hours) or age (in years). Crude (univariate) and adjusted (multivariate) coefficients are shown for each model. Variables associated with a statistically significant increase in pre-hospital timespan in the multiple linear regression model are set in bold.
