Common Treatment to Prevent Recurrent Miscarriage Doesn't Work

Of the 171 women who completed the study, 36% of the treated participants
met with success, compared with 48% of the controls -- roughly indicating that
no treatment was better than the treatment studied. This trend continued among
women who became pregnant: 46% of the treatment group sustained their
pregnancies compared with 65% of the control group.
"Our final sample was smaller than we had originally planned," Ober
tells WebMD. "However, the pregnancy loss rates were so much higher in the
treated group that, even had we been able to continue to recruit more subjects,
the best we could have hoped for was no difference between the groups."
Instead, a significantly higher rate of success was found in the control
"This study was very well done, by being placebo-controlled, and serves
as a model for other studies," Sandra Carson, MD, tells WebMD. "All of
our studies on spontaneous abortion need to be done just like this."
Carson, an infertility specialist and a professor of obstetrics and gynecology
at Baylor College of Medicine in Houston, was contacted by WebMD for comment
and was not involved in the study.
