OLS Restimates of the Relationship between Probability of Receiving Catheterization and HRR Patient Characteristics

HRR-Level Independent Variables:	Probability of Receiving Catheterization	Probability of Receiving Catheterization
Average propensity to get CATH	0.529 (0.172)	0.575 (0.167)
Percent under age 65		0.150 (0.135)
log of resident population		−0.003 (0.005)
log of per capita income		0.024 (0.024)
N	138,873	138,873

Notes: Table reports OLS estimates of the relationship between a patient receiving Catheterization and the average appropriateness for Catheterization in an HRR. Regressions control for patient risk-adjusters, and standard-errors are clustered at the level of HRRs.
