Survival in HNM patients: Kaplan-Meier curves for OAS (Fig. 4A) and RFS (Fig. 4B) differentiated by accomplished SLNB as well as result of SLNB. A: (HR = 6.386, CI = 2.727–14.956, p < 0.001), B: (HR = 14.442, CI = 6.974–29.906, p < 0.001). Figure 4C: Kaplan-Meier curve for OAS in UICC stage II patients, differentiated whether SLNB was applied or not (HR = 0.360, CI = 0.134–0.962, p = 0.042); Fig. 4D: Forest plots for SLNB as a predictor for distant metastasis in HNM (pos. SLNB vs. no SLNB: HR = 28.458, CI = 12.463–64.978, p < 0.001) (neg. SLNB vs. no SLNB: HR = 2.149, CI = 1.041–4.433, p = 0.038)
