Kaplan-Meier estimates of PFS-I and PFS-M stratified by curator for NSCLC and CRC: (A) PFS-I NSCLC, (B) PFS-I CRC, (C) PFS-M NSCLC, and (D) PFS-M CRC. Survival curves are stratified by the primary curator and secondary curator among records that underwent double curation for the purposes of assessing reproducibility. Note that curves are not intended to describe estimates of time to event end points, but to demonstrate the assessment of reproducibility of curation of time to event end points across curators. CRC, colorectal cancer; NSCLC, non–small-cell lung cancer; PFS-I, progression-free survival according to imaging; PFS-M, progression-free survival according to medical oncologist.
