Follow-up study phase was associated with increased odds of reporting any OTC NSAID risk awareness ( AOR = 2.99 , P < 0.001 ) , but the patient activation intervention and intervention by study phase interaction were not significantly associated with patient-reported awareness of any OTC NSAID risk ( AOR = 0.98 , P = 0.929 ; AOR = 0.87 , P = 0.693 , respectively ) .
