From: Treatment response lowers tumor symptom burden in recurrent and/or metastatic head and neck cancer
Changes in overall symptom burden in responders and non-responders (ANCOVA analysis). Changes from baseline were analyzed at the three time points “first post-baseline assessment”, “best post-baseline assessment” and “assessment at treatment end” in responders and non-responders. Negative values indicate improved symptoms and positive values deteriorated symptoms. n indicates the number of analyzed questionnaires. Results show the overall VAS score calculated from the ten single symptom VAS scores
