Kaplan-Meier curves for overall mortality (P<.0001, log-rank test) by smoking status prior to diagnosis

Table that corresponds to Figures 1 and 2:

Figure 1 and 2: Number at risk	0 years	5 years	10 years	15 years	20 years
Never smoker	2449	1723	816	256	16
Former smoker	2640	1870	904	264	12
Quit <10 years*	297	216	124	35	4
Quit 10+ years*	2063	1473	695	207	9
Current smoker	277	194	104	38	3

^*

These numbers do not equal the total number of former smokers because 280 former smokers are missing data on years since quitting smoking.
