*Continuous scale from 1 to 7, with 7 as the most urgent. Hazard ratios are for each 1 unit change in the urgency score
† Compared to reference of 20-39 yr female
** compared to income quintile 1, which is lowest income category.
HR is hazard ratio - HR greater than 1 indicates shorter wait time; CI is confidence interval.
