FIG 3.

Swimmer plot of severe oral mucositis scores for the subsets of patients in (left) the placebo arm (n = 45) or (right) the 90-mg arm (n = 35) who had at least one WHO oral mucositis score of grade 3 or 4. Each horizontal lane represents the experience of an individual patient. Time on radiation therapy or after radiation therapy is indicated at the top, for which the vertical line denotes the end of intensity-modulated radiation therapy. Yellow, WHO grade 3; red, WHO grade 4; purple, WHO grade 0 to 2. WHO scoring was done twice per week during radiation therapy, then once per week after radiation therapy in patients who returned for follow-up for up to 8 weeks or until the WHO score was 0 or 1.
