Relationships of percentage of hybrid MHC IIA/X and I/IIA fibers to indices of 6-min walk performance in cancer patients. Note that there is n = 13 for the top panel and n = 10 for the bottom panel. The reduced n in these analyses reflects the fact that MHC IIA/X and I/IIA fibers were not observed in all cancer patients. Data for MHC I/IIA fibers in cancer patients was log10 transformed to achieve normality.
