Fig 5. Tumor M2-PK accurately distinguishes controls from patients with bladder cancer.

Voided urine was collected from either control volunteers or bladder cancer patients. Tumor M2-PK was performed at various dilutions on urine and M2-PK concentrations were determined (A). Receiver operator characteristic curve analysis was used to assess the capacity of M2-PK to distinguish between control and bladder cancer patients (B).
