*Unless stated otherwise.
†All patients identified before weighting were included in the analyses. The number of patients indicated represents a weighted total.
‡Standardized differences are less sensitive to sample size than traditional hypothesis tests. They provide a measure of the difference between groups divided by the pooled standard deviation; a value greater than 10% is interpreted as a meaningful difference between the groups.
§Income was categorized into fifths of average neighbourhood income on the index date.
