Correlation of urinary midkine levels with tumor grade. Following the histopathological examination of the resected tumor tissue, bladder cancer patients were classified regarding their tumor grade in (A) low-grade and high-grade (WHO 2004), and (B) G1, G2, G3 (WHO 1973, available only for 91 patients). The control group included patients with chronic cystitis, renal cell carcinoma, cystic disease and nephrolithiasis. The tables show the total number of patients per group, as well as the corresponding median midkine level. Data were normalized to urinary creatinine (µg/g creatinine). P<0.05 was considered statistically significant (Mann Whitney U test). WHO, World Health Organization.
