SIDs cases not further defined assume <1 year Included study types: Case control studies studies were conducted between 1984 and 2006. Quality of included studies: Provided inclusion criteria for including studies, no included study failed on any of these. There was a moderately large degree of heterogeneity in the analysis (I2 48.5 p= 0.04 with one study excluded; 57.3 p=0.009 when included – OR for bed sharing when this study excluded not provided). Synthesis: Meta-analysis Findings: Eleven studies met inclusion criteria and were included in the final The infant regardless of smoking status and routine sleep location. These have not been included because they used data from studies other than the 11 included studies and no explanation why or detail of these other studies was included in the text. Lack of detail on study quality reduces confidence in findings. There is an overlap with data included in the Carpenter 2013 but some more recent case control studies are included. Did not analyse individual level data as in Carpenter so could not adjust for maternal alcohol and drug use found to be a strong enhancing factor in Carpenter Some included studies counted sofa analysis.
