This tool helps clinicians to understand the risk for worsening kidney function over a period of 5-7 years post-diagnosis. This scoring can be conducted by the physician at the time of diagnosis, while it requires only routine clinical data, laboratory results, and biopsy findings. This system also is applicable to adults and pediatrics of all ethnicities.
