Are pill counts valid measures of compliance in clinical obstetric trials?

Academic Article


  • We compared pill counts with a biochemical measure of complicance 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. © 1993.
