Multivariate logistic regression analysis of forest plot with additional indicators. Major axis / Minor axis (> 1.16), tumor-renal interface (> 22.3 mm), and SNRR (> 0.16) were identified as independent risk factors, which could be utilized to develop separate prediction models for HG and MCAR. SNRR = standardized nephrographic reduction rate, HG = heterogeneity grade, MCAR = mass-to-cortex corticomedullary attenuation ratio
