  1. Note: There are 112116 observations when decomposing the inequality of probability of inpatient visit and inpatient visits in 2003, and 3742 observations when decomposing the Per-visit hospitalization days in 2003. Marginal effects which differ significantly from zero (at p < 0.05) in the regressions are showed with *.
