A simple score, derived by allocating points to a selection of factors which influence the outcome of pre-term labour, was found to relate to the success of treatment. Used as a measure of the situation before therapy, this score can define a baseline allowing a realistic comparison of therapeutic methods. In this series, despite treatment, a large number of patients still were delivered before term and within a few days of admission to hospital. Thus it would seem that although drugs suppress uterine activity, they cannot neutralize the adverse effects of other factors associated with pre-term labour.
通过对一系列影响早产结局的因素进行评分得出的一个简单分数，被发现与治疗的成功与否相关。该分数用作治疗前情况的衡量指标，可以定义一个基线，以便对治疗方法进行实际比较。在这个系列中，尽管进行了治疗，但仍有大量患者在入院后几天内早产。因此，似乎尽管药物可以抑制子宫活动，但它们无法抵消与早产相关的其他因素的不利影响。
