  • * Criterion B was not administered to 6 patients in the SSc sample and 3 patients in the cancer sample who did not meet the 5-symptom criterion in the original definition. For estimation purposes, it was assumed that it would have been met based on 84% and 90% rates of meeting Criterion B in SSc and cancer samples, respectively. SSc: systemic sclerosis.
