  1. Note: The samples in the columns are non-overlapping (or minimally overlapping) samples and do not violate SEER-Medicare cell size suppression rule. Variables controlled in some of the 4 matches but allowed to vary naturally in other matches. The “Hispanic patients” column reports the statistical numbers for all Hispanic patients in the data set. The “Treatment-matched” column reports the statistical numbers for the closest non-Hispanic white match, namely the treatment match (which also controls for presentation, SES, and demographic variables); the “Presentation-matched” column also controls for SES and demographic variables; the “SES-matched” column also controls for demographic variables. The “All Whites-unmatched” column reports data for all non-Hispanic whites in the data set without matching. Results for each variable that appear to the left of the bold vertical line are for variables included in the match designated by the column. Results to the right of the bold vertical line are for variables not used in the match designated by the column. Percentages or rates bolded imply statistically significant (P < 0.05) differences between Hispanics and non-Hispanic whites.
