aANCOVA model adjusted for gender, age, space closure, and treatment mechanic,.bbinary logistic regression adjusted for gender and age, cregression coefficient: average difference in number of visits / duration of treatment [in months] between the Non-SL (reference group) and the SL group (comparison group), dOdds ratio: chance of extraction occurring in the SL group compared to the chance of extraction occurring in the Non-SL group. An OR of 1 indicate equal chances in both groups, OR > 1 indicate higher chance in the SL vs. non-SL group, OR < 1 indicate lower chance in the SL vs. Non-SL group, d Reference category.
- CI confidence interval, OR: odds ratio, rRR: relative root resorption, sEARR: severe external apical root resorptions, SL: self-ligating.
