  1. Abbreviation: CI, confidence interval. *P<0.001; **P<0.002 significance for individual variable odds ratios based on Wald’s test. P-value is based on likelihood Ratio tests of heterogeneity of each successive model to the model prior. P-value for model 1 is the likelihood ratio test of model 1 compared with a model without any variables added. Ref: is the reference category to which the odds ratios are given.
