In the training cohort, shorter CSS was associated with lymphovascular embolization (a) (P < 0.001), perineural invasion (b) (P < 0.001), and pathological grade (c) (P = 0.004). In the external validation cohort, shorter CSS was associated with lymphovascular embolization (d) (P < 0.001) and perineural invasion (e) (P < 0.001), but not with pathological grade (f) (P = 0.224)Back to article page
