  1. Others in marital status include divorced, widowed, unmarried, and unknown marital status. Superscripts a, b, c, d are used to indicate significant differences between groups. If two groups have different superscripts, it means there is a significant difference between them (To control the errors caused by multiple comparisons, we adopted the Bonferroni correction method, dividing the original significance level (α = 0.05) by the number of tests to obtain the corrected threshold α′ =0.05/6 = 0.0083). Superscript e: the value of Cochran-Armitage trend test; Superscript f: multivariable logistic regression (P < 0.001). - : variables not entered into the logistic regression model.
