The table shows the results of multivariate logistic regression analyses using age, BMI, change in TEMPS-A scores, socio-economic and clinical history parameters as predictor and clinical pregnancy as outcome variables. Affective temperaments were fit into the multiple regression analyses separately. OR odds ratio, CI confidence interval, BMI body mass index. The bold values in the table represent significant findings.
