Maternal education (OR: 1.56 (95% CI: 0.98–2.46); p = 0.057), was marginally significant and was included in the multivariate analysis; additionally low birth weight showed marginal significance (OR: 2.90 (95% CI: 1.12–7.44); p = 0.07), however the large number of missing values for birth weight (19.2% missing) and paternal age (10.9% missing) reduced the potential value as predictive factors and were therefore not included in the multivariate analysis.
