Abstract
We compared pill counts with a biochemical measure of compliance in 283 women who participated in a randomized double-blind trial that evaluated the efficacy of low-dose aspirin in the prevention of preeclampsia. Subjects whose pill counts indicated a usage > 100% were less compliant than women with lower pill counts.
