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.Keywords: Contraception; Diseases; Family Planning; Iud; Logistic Model; Mathematical Model; Models, Theoretical; Population At Risk; Pregnancy Complications; Pregnancy, Ectopic--etiology; Research Methodology; Sampling Studies; Scoring Methods; Studies; Survey Methodology; Surveys
