Time interval is the number of days between the pretreatment scan and follow-up scan. Change in lymph node volume was assessed at this time. Lymph node reduction is the percent change in volume of the lymph node between the pretreatment and follow-up scan. Numerical data are mean ± standard deviation or median [interquartile range].
