  1. aAdjusted odds ratio is defined as the full regression model, with all variables included in the analyses. Full individual registry analyses including total numbers and crude odds ratios can be found in Additional file 2. Owingto their passive consent process, California was not included in the analysis as numbers of nonconsenting cases (n = 26) were too small to examine.bAll consenting cases provided by the Idaho registry were of non-Hispanic ethnicity. Thus, ethnicity was excluded from Idaho analyses.cOwing to HIPAA privacy concerns, New Mexico did not provide age, race, or rural or urban status of nonconsenting individuals. Thus, these categories are excluded from New Mexico analyses.dDifferent registries provided eligible cases from different diagnosis years based on consideration of total number of eligible cases. Thus, referent for diagnosis year differs by registry.
