Figure 1. Escalating Mortality Risk With Increase in Metastatic Lymph Node Number.

Figure 1.

Escalating adjusted hazard ratio (HR) with increasing number of positive metastatic lymph nodes (LNs) in hypopharyngeal and laryngeal cancers. Gray dashed lines represent estimated 95% CIs of the predicted HRs. Black solid line represents multivariable smoothed restricted cubic spline plot of the natural logarithm of adjusted HR vs the number of positive metastatic LNs. Blue vertical line represents the estimated change point at 5 positive LNs.
