Notes: Standard errors are reported in brackets below the estimated coefficients, but are not clustered at the paramedic level, and are therefore likely to underestimate the true variability of the estimated coefficients. Inferences based on them should therefore be made with caution. *, **, and *** indicate significance at 10%, 5%, and 1% levels, respectively. See Table 2 notes for list of controls.
