Figure 4From: Toll-like receptor 4 single-nucleotide polymorphisms Asp299Gly and Thr399Ile in head and neck squamous cell carcinomasTLR4 Arg299 allele impact on tumor recurrence stratified by adjuvant systemic therapy. (A) no systemic therapy and (B) adjuvant systemic therapy; in patients according to TLR4 allele status (TLR4 Asp299Asp vs. TLR4 Asp299Gly). P-values from the log-rank test are indicated.
