In total, 3496 women were included in the study. To examine the relationship between DII, EDII and infertility, a weighted multivariable logistic regression analysis using continuous factors or categorical variables grouped by quartiles was conducted. Using subgroup analysis stratified based on DII and infertility features, the association between DII and infertility has been further studied. In order to determine whether there was a nonlinear relationship between DII and infertility, restricted cubic spline (RCS) analysis was carried out.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>For statistical analysis, a total of 3496 individuals \u2014 367 patients with infertility and 3129 persons without infertility \u2014 were included.
