Legend: A one-way ANOVA was used for the comparison of age and PMI between the different groups, and Fisher's exact test was used for the comparison of the percentage of gender and prematurity between groups. These comparisons do not include the non-SIDS control group, which is composed of the acute and chronic controls and the cases of acute asphyxia. Abbreviations: N, sample size; PCA, postconceptional weeks; GA, gestational age; PNA, postnatal age; PMI, post-mortem interval.
