Fig. 2From: Radiation-induced lymphopenia correlates with survival in nasopharyngeal carcinoma: impact of treatment modality and the baseline lymphocyte countKaplan-Meier curves show the comparison of the cumulative incidence of grade 3–4 (G3–4) radiation-induced lymphopenia (RIL) (absolute lymphocyte count [ALC] < 0.5 × 109/L) after intensity-modulated radiation therapy (IMRT) and 2D-conventional radiation therapy (2D-CRT)Back to article page
