OR Odds Ratio, 95 % CI 95 % confidence interval

ORs are based on multinomial logistic regression models, each containing the specific variable itself, the variable consent yes/no, and the interaction term of the two variables

^aOnly statistically significant interactions with consent yes/no are presented (p < .05)
