abortion {etm} | R Documentation |
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, leading to a competing risks situation. Moreover, data are left-truncated as women usually enter the study several weeks after conception.
