Table 3.
Association of SIDS (n = 50) with covariates compared to healthy Dutch controls (n = 2,438); included were only cases and controls where it was reported that no maternal prenatal smoking is involved. P-values and odds ratios for entire case group. P-values calculated with two-tailed Fishers’ exact test, OR and 95% CI for OR of the binary logistic regression of all covariates. Prone sleeping 1 is primary prone sleeping; prone sleeping 2 is secondary prone sleeping; supine sleeping is indicator. Education parents 1 is both low; education parents 2 is one low; both high educated is indicator. Ethnical origin parents 1 is one European Caucasian, one non- European Caucasian; ethnical origin parents 2 is both non-European Caucasian; both European Caucasian is indicator
