Figure 1. Box and Whisker Plots of Outcomes.

Box and whisker plots of absolute neutrophil count (ANC), absolute lymphocyte count (ALC), and ratio of neutrophils to lymphocytes (NLR) at pretreatment, the ALC nadir during treatment and 3, 6, and 12 months after radiotherapy (RT) start. Median is denoted by the line inside the box; interquartile range, box. The whiskers include 95% of a normally distributed range around the median. Open circles indicate outliers (to convert ALC and ANC to ×10⁹ per liter, multiply by 0.001).
