Notes: All estimates were weighted using the propensity score-derived weight for the matched sample. All statistical tests adjusted for the clustered and stratified design of MEPS using the method of balanced repeated replication (BRR), which also accounts for lower levels of clustering at the household and individual level.
*p<.10, **p<.05, and *** p<.01 for difference in means between the claims and MEPS. (Means estimated with Stata's SVY: MEAN command with BRR option; t-test of equality of means performed using the LINCOM postestimation command.)
# p<.10, ## p<.05, and ### p<.01 for difference in ratio by group characteristic. (Ratios estimated with Stata's SVY: RATIO with BRR option; Wald test that ratios are all equal within group performed with the TEST postestimation command.)
FPL, federal poverty line; MEPS, Medical Expenditure Panel Survey; MSA, metropolitan statistical area.
