Although the background of individuals showed significant variations in age, ECOG PS, and EGFR mutational subtype between 1G and 2G, these factors were included in the modifying factors in the propensity rating. Our study indicated the 2G EGFR\TKI group experienced statistically longer OS and TTF compared with the 1G EGFR\TKIs actually after modifying these factors by propensity score. Multivariate analysis showed HR of 0.756 having a value of .0432 (Table?S2).

To our greatest knowledge, the test size of our research may be the largest in the retrospective research to evaluate 1G and 2G EGFR\TKIs, including over 200 individuals who received 2G EGFR\TKI.
