Each foot was assessed live, from photographs 2 weeks later, and again 4 weeks later for the presence of an ulcer, abundant callus, or the absence of signs. Each foot was assessed by four independently operating foot care specialists. Agreement scores were calculated using\n                      <jats:italic toggle=\"yes\">\u03ba<\/jats:italic>\n                      values (range, 0\u20131).
