All ordinal variables are coded in increasing order
aThe table reports odds ratios of all variables selected into each model using AIC model selection; variables were selected to maximize model fit, and selection does not indicate significant association. Full results including all variables considered for each outcome are available in Table B of the online supplement
bAll 420 respondents did not complete every survey item; therefore each model was constructed with a subset of respondents who completed the survey items included in the model. No responses were imputed
cThe percentage of respondents whose answer to the survey item of the corresponding outcome was coded as 1
