abortion

Outcomes of pregnancies exposed to coumarin derivatives. The aim is to
 investigate whether exposition to coumarin derivatives increases the
 probability of spontaneous abortions. Apart from spontaneous abortion,
 pregnancy may end in induced abortion or live birth. Moreover, data
 are left-truncated as women usually enter the study several weeks
 after conception.
