| Target lesion size | Ex19del/L858R status by cobas plasma test | ||
|---|---|---|---|
| Positive (n = 359) | Negative (n = 124) | Unknown (n = 72) | |
| Median baseline target lesion size (mm) | 55 | 53 | 47 |
| Range (mm) | 10–207 | 10–126 | 10–176 |
| Pa | <0.001 | ||
NOTE: Ex19del, exon 19 deletion mutation.
