BWAT-CUA scores versus total BWAT scores in a clinical study. Images were obtained before and after 12 weeks of open-label treatment with the hydroxyapatite crystallization inhibitor, SNF472. Investigators rated all 13 items of the BWAT prospectively and the total BWAT score was calculated for the primary efficacy endpoint of calciphylaxis wound healing. BWAT-CUA scores were calculated ad hoc from the eight items selected for this tool.
