The combined sequence was modeled to obtain the final radiomics signature, and the final radiomics signature was used as an independent predictor that combined with clinical factors (gender, hypertension, urinary albumin, eTKV, urinary white blood cells, urinary red blood cells, maximum cyst length, maximum bleeding cyst length) to screen clinical variables by using logistic regression univariate analysis. Here, ALB is linked to Hypertension.
