Fig 1.
Cumulative risk of recurrence and death during 10 years' follow-up among patients with laryngeal squamous cell carcinoma.
Fig 2.
Cumulative risk of recurrence by subsite of laryngeal squamous cell carcinoma during 10 years' follow-up.
P value is achieved from the Pepe and Mori test comparing the cumulative risk of glottic versus supraglottic cancer.

Table 3.
Competing risk regression model to evaluate the effect of selected covariates on the risk of recurrence among patients with glottic laryngeal squamous cell carcinoma during 10 years' follow-up (n = 1127; 243 recurrences and 425 deaths).
SHR, sub-distribution hazard ratios; CI, confidence interval.
Table 4.
Competing risk regression model to evaluate the effect of selected covariates on the risk of recurrence among patients with supraglottic laryngeal squamous cell carcinoma during 10 years' follow-up (n = 437; 113 recurrences and 227 deaths).
SHR, sub-distribution hazard ratios; CI, confidence interval.
Table 5.
Type of recurrence stratified by subsite at diagnosis.
Chi-square test, used to determine whether the site of recurrence differed between subsites, yielded p<0.01.
