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