The original version of this Article contained an error in the title of the paper.

“Real-world evidenceand clinical observations of the treatment of advanced non-small cell lung cancer with PD-1/PD-L1 inhibitors”

now reads:

“Real-world evidence and clinical observations of the treatment of advanced non-small cell lung cancer with PD-1/PD-L1 inhibitors”

This has now been corrected in the PDF and HTML versions of the Article.
