Establishment and validation of a predictive nomogram model for non-small cell lung cancer patients with chronic hepatitis B viral infection

Table 4 Cox regression analysis for groups based on the model in the primary cohorts

Groups	OS mean	1-year (%)	3-years (%)	5-years (%)	Sig.	HR	95% CI for HR
Groups	OS mean	1-year (%)	3-years (%)	5-years (%)	Sig.	HR	Lower	Upper
Low	75.976	95.9	68.9	55.4	–	–	–	–
Intermediate	38.839	76.7	37.2	14.0	< 0.001	4.098	2.274	7.385
High	13.852	45.8	8.3	0.0	< 0.001	15.318	7.739	30.320

Groups were divided by cutoff values of total prognostic scores (TPS) cumulated from nomogram we designed. (TPS ≤ 13.5, 13.5 < TPS ≤ 20.0, TPS > 20.0) (group lowest risk, intermediate risk and high risk with 74, 43 and 24 patients, respectively.). CI confidence interval, HR hazard ratio, OS overall survival
