OR: odds ratio; CI: confidence interval; ∗adjusted analysis: All variables were included in the adjusted analysis regardless of 𝑃 value in the crude analysis. Model variables were retained with 𝑃 value ≤ 0.20; superscript numbers (1, 2, 3, and 4) represent input of variables in the hierarchic model for the adjusted analysis.
