Ethnicity showed a trend toward significance before matching ( p = 0.058) but no significant differences after matching ( p = 0.938).
Additionally, the Hui ethnic group showed a trend toward a lower likelihood of receiving combination therapy, although this did not reach statistical significance in the multivariate analysis (OR: 0.356, 95% CI: 0.106–0.986; p = 0.065).
