^aAll values are percentages and may not add to 100 due to rounding. Neighborhood deprivation is derived from the Area Deprivation Index score, which was split into five equally sized quintiles. The least (1st) and most (5th) disadvantaged quintiles are presented here. The 2nd through 4th quintiles are not presented. All least disadvantaged/most disadvantaged comparisons are significant at a level of P < 0.001.
