Ordinal logistic model: association of genetic and clinical risk factors with the severity of hyperbilirubinemia according to the TSB level.

*Abbreviation: GW: Gestational week; F: Model fitting statistic; P: Pearson χ2 statistic; D: Deviance χ2 statistic; L: Parallel line test statistic. C: Cox and Snell; N: Nagelkerke; M: McFadden. The parallel line test was tested using the χ2 statistic. A non-significant P value indicated that the odds ratio could be interpreted as constant across all possible cut-off points of the outcome (Null hypothesis). This Null hypothesis was applied for only the evaluation of the location model. Pearson χ2 and Deviance χ2 were used to test the Goodness of fitting. If the P value of the χ2 statistic was less than 0.05, we rejected the null hypothesis and concluded that there was a significant difference between the observed and expected values. The larger the R2, the better the model fit.
a The feeding (1) group was comprised of breast or mixed breast and formula fed infants; the feeding (2) group was comprised of exclusively formula fed infants.
