Notes: All estimates and confidence intervals (CI) are corrected for the complex survey design of the MEPS and for multiple imputation of missing data. Regression adjusted expenditure levels were estimated using a generalized linear model with a log link and a gamma error distribution. Source of data: Medical Expenditure Panel Survey (MEPS). N/A=There were too few inpatient and outpatient events to estimate.
