Figure 1. Head and Neck Cancer-Specific Symptoms by Smoking Status.

Figure 1

Average scores and 95% confidence intervals are presented for each smoking status group. Each measure assessed symptom over the past week on a scale from 0 to 100 with higher scores reflecting worse problems on the European Organization for Research and Treatment of Cancer Head and Neck Module. Kruskal-Wallis tests were used to examine the overall association between smoking status (current/recent, former, never smokers) and symptom factors.
