In a prospective study, 300 women were treated during 1976 to 1978 alternatingly with hormones or placebo, the comparability of both groups being established in respect of certain influencing factors. No statistically confirmed difference was found in the total success rates of both types of treatment. The age of the pregnant women, and any previous abortions, did not represent any risk factor for imminent abortion. A better success rate was obtained with gestagen therapy, depending on the gestation period. (= 9th week of pregnancy).
在一项前瞻性研究中，1976年至1978年期间，300名女性被交替给予激素或安慰剂治疗，两组在某些影响因素方面具有可比性。两种治疗方式的总成功率在统计学上未发现显著差异。孕妇的年龄以及既往流产史，均不构成即将流产的危险因素。根据妊娠期（=妊娠第9周），孕激素治疗获得了更好的成功率。
