Prevalence of and Adjusted Risk for Medication Restriction among High-Risk Groups, by Prescription Coverage

	Restricting Medications, %*			Adjusted Odds for Medication Restriction (95% Confidence Interval)†
Characteristic	No Coverage	Partial Coverage	Full Coverage	No vs Full Coverage	No vs Partial Coverage
Minority ethnicity	20.9	7.5	3.7	10.3 (4.4 to 24.4)	4.3 (2.6 to 7.3)
Income <$10,000	15.6	7.7	2.3	14.8 (6.7 to 32.6)	3.2 (2.2 to 4.6)
Monthly out-of-pocket prescription drug cost >$100	13.4	4.3	‡‡	‡‡	3.8 (2.2 to 6.5)

^*P < .001 for comparisons within each group by independent samples t tests (no vs partial coverage, no vs full coverage).

^†Multivariate odds ratio, adjusting for all variables independently associated with medication restriction in seniors without prescription coverage, except out-of-pocket prescription drug cost.

‡Out-of-pocket prescription drug costs not assessed for subjects with full coverage.
