People with nonrheumatic atrial fibrillation who have had a transient ischemic attack or minor ischemic stroke are at risk of recurrent stroke. ⋯ Aspirin may reduce the risk of vascular events in people with nonrheumatic atrial fibrillation, but the effect shown in the single trial was not statistically significant.

ReviewWITHDRAWN: Clomiphene citrate for ovulation induction in women with oligo-amenorrhoea.
The administration of clomiphene citrate is followed by an enhanced release of pituitary gonadotropins resulting in follicular recruitment. After the drug is stopped, there is continuing secretion of estradiol, selection of the dominant follicle and, in successful cases, ovulation. Clomiphene is indicated as the initial treatment in the majority of women with amenorrhoea and oligomennorhoea. In women with irregular ovulation it seems to re-establish typical frequency of ovulation. Its effectiveness in oligo-amenorrhoeic women was tested in a number of randomised controlled trials at that time. These trials form the basis for the following review. ⋯ Clomiphene citrate (at doses between 50 to 250 milligrams per day) appears to be an effective method of inducing ovulation and improving fertility in oligo-ovulatory women. However adverse effects include possible ovarian cancer risk and risk of multiple pregnancy.
