R Documentation
Data on 996 initial Percutaneous Coronary Interventions (PCIs) performed in 1997 at
the Lindner Center, Christ Hospital, Cincinnati.
Description
Data from an observational study of 996 patients receiving a PCI at Ohio Heart
Health in 1997 and followed for at least 6 months by the staff of the Lindner Center.
This is a landmark dataset in the literature on propensity score adjustment for
treatment selection bias due to practice of evidence based medicine; patients receiving
abciximab tended to be more severely diseased than those who did not receive a IIb/IIIa
cascade blocker.
