a numerical trendP=0.17
A comparison was performed between the patients with the exon 19 deletion and those with the L858R mutation and identified a numerical trend that favored the exon 19 deletion compared with the L858R mutation in the TTD and OS {TTD: HR =2.31 [95% confidence interval (CI): 0.69–7.70]; P=0.17; OS: HR =2.39 (95% CI: 0.72–7.94); P=0.16} ( Figure S2A,S2B ).
