title: Background factors of ectopic pregnancy. II. Risk estimation by means of a logistic model.
abstract: Based on the frequency distribution in a previous case-control study of ectopic pregnancy in Sweden, the prognostic value of a number of risk factors was analysed. A logistic procedure was applied in a stepwise manner, resulting in a risk-scoring model in which the probability of ectopic pregnancy can be determined on the basis of four background factors.
