  1. All odds ratios are adjusted for gender (using men as the reference category). For the adjusted odds ratios both p-values and 95% confidence intervals (CI) are presented. The total number of respondents varied between N = 737 – 885, because of incomplete data. Estimates were not calculated for explanatory variables with five or fewer exposed cases.
