In a large-scale collaborative study of over 17,000 patients, one-year major amputation rates rose from 15% in WIfI stage 1 to 55% in stage 4. Furthermore, WIfI clinical stage 3 or 4 is consistently associated with significantly higher hazards for all-cause and cardiac mortality compared to lower stages.
