In model 1, after adjustment for age and eGFR < 90 mL/min/1.73m2, trace urinary albumin and positive urinary albumin were both significantly correlated with CIN non-recovery, and the odds ratios (OR) values were 3.44 (95% CI 1.38–8.33) and 5.66 (95% CI 2.49–13.06), respectively. Here, ALB is linked to cervical squamous intraepithelial neoplasia.
