I am reviewing a study. It's authors wanted to investigate which of the care settings were more often used by women and which by men. Adjusting was done for age, comorbidity status. There were a total of 10 care settings. Thus, they did the following:
Binary logistic regression
sex ~ care_settings + covariates for adjusting
But IMHO they should have been used multiple logistic regression
care_settings ~ sex + covariates for adjusting
Could you have a comment on that. Is their approach correct?
