Sample size for the logistic regression model was lower due to list-wise deletion. The 192 respondents excluded from this analysis did not differ from the rest of the sample on any of the model variables and differed on only one of the study variables (marital status); they were more likely to be single/divorced/separated/widowed (Fisher exact test, p = 0.009, 2-tailed).

OR, odds ratio; CI, confidence interval.
