Table 5.

Association of two histological defined categories of SIDS with covariates compared to healthy, age-matched Dutch controls (n = 2,841). P-values and odds ratios for the two largest SIDS categories defined by histological findings; genuine SIDS, no findings that might have had any influences on survival; SIDS with minor infections, e.g. laryngitis, urine bladder infection, etc. 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
