Kaplan-Meier cancer-free survival curves in the exploratory series of 82 patients with laryngeal dysplasias categorized by NANOG protein scores (A) or NANOG protein expression dichotomized as strong (score 2) versus negative to moderate expression (scores 0–1) (B). Kaplan-Meier cancer-free survival curves in the validation series of 86 patients with laryngeal dysplasias categorized by NANOG protein scores (C) or NANOG protein expression dichotomized as strong (score 2) versus negative to moderate expression (scores 0–1) (D). P values were estimated using the log-rank test.
