Following publication of the original article [1], the authors identified an error in the caption of table 4.

In the published article [1], the title of Table 4 is “Progression-free and overall survival of RET + versus RET- cohorts from start of first-line therapy,” which should be corrected to read “Progression-free and overall survival of RET- versus RET + cohorts from start of first-line therapy,” (correction in bold) to correctly indicate the direction of the hazard ratios.
