Overall Survival Depends on the Follow-up Strategy

Follow-up strategy	Five-year OS (%)	OS (months) Mean (95% CI)	p
Follow-up type
Standard (n = 219)	90.9	154.5 (146.8, 162)	0.538
Alternative (n = 199)	90.8	151.9 (146.4, 157.4)
Surveillance chest X-ray
Yes (n = 167)	90.9	151.86 (145.9, 157.8)	0.569
No (n = 245)	90.8	154.8 (147.6, 162)
Surveillance LFT
Yes (n = 125)	92.6	155.97 (150.25,161.68)	0.116
No (n = 287)	90.4	153.96 (147.7, 160.2)
