Fig. 4

The bar graph demonstrates the incidence of osteoradionecrosis according to factors that were positive in multivariate analyzes. Note: A; V64 Gy, red bar: < 27%, blue bar: ≥ 27%, B; Pre-C-CRT tooth extraction, red bar: < 5, blue bar: ≥ 5, C; Post-C-CRT tooth extraction, red bar: Absent, blue bar: Present, D; MMD, red bar: < 50.6 Gy, blue bar: ≥ 50.6 Gy, E; C-CRT to tooth extraction interval, red bar: > 5.5 mo., blue bar: ≤ 5.5 mo., F; HPR, red bar: ≤ 0.48, blue bar: > 0.48. Abbreviations: C-CRT concurrent chemoradiotherapy, Gy Gray, HPR hemoglobin-to-platelet ratio, MMD mean mandibular dose, mo months, ORN osteoradionecrosis, V64 mandibular volume receiving ≥ 64 Gy
