Table 4 Survival time estimates in months for progression-free survival, overall survival and loco-regional control.

From: Pre-radiotherapy plasma carotenoids and markers of oxidative stress are associated with survival in head and neck squamous cell carcinoma patients: a prospective study

Survivala

All patients

n = 78

Only radiotherapy

n = 48

Post-operative radiotherapy

n = 30

Progression-free

23.8 (18.2-29.4)

31.5 (26.0-36.9)

Overall

34.7 (30.6-38.9)

29.1 (23.9-34.3)

42.8 (38.4-47.2)

Loco-regional control

32.8 (28.6-37.1)

29.2 (23.4-35.0)

34.5 (29.7-39.4)
