Multivariable ordinal logistic regression analysis was conducted. Odds ratios greater than one indicate association with higher career satisfaction, and odds ratios less than one suggest association with lower career satisfaction.

^aMeasured as an ordered categorical variable from 1 to 5 with greater values indicating higher career satisfaction (1 = “very dissatisfied”; 5 = “very satisfied”).

^bOR: odds ratio; 95% CI: 95% confidence interval.

^cLess than 7% of the respondents had missing data on one of more of the variables and hence were not included in the regression analysis.
