The Variation of Peripheral Inflammatory Markers in Vocal Leukoplakia before and after Recurrence and Canceration

Figure 4

Comparison of presurgical NLR (a, d, g), PLR (b, e, h), and MLR (c, f, i) according to pathological development status with the WHO 2017 Blue Book standard in recurrence group. (a–c) With pathological progress from low risk to high risk. (d–f) With no pathological progress. (g–i) With pathological release from high risk to low risk. NLR: neutrophil-to-lymphocyte ratio. PLR: platelet-to-lymphocyte ratio. MLR: monocytes-to-lymphocyte ratio. Before: before it crossed the line of two-tier system. After: after it crossed the line of two-tier system.
