Distribution of patients by treatment group stratified by age group. This double bar graph represents the distribution of patients who underwent TLM or RT stratified by their age group. 23 patients were treated with TLM, with 4 less than 65 years old (5.3 %), 8 patients 65–75 years old (10.7 %), and 11 patients greater than 75 years old (14.7 %); and 52 patients were treated with RT, with 21 patients less than 65 years old (28 %), 20 patients 65–75 years old (26.7 %), and 11 greater than 75 years old (14.7 %). A statistically significant difference in the distribution of age group across treatment group was observed (χ 2 = 6.455, p = 0.04)
