Participants with neither disease progression nor death were censored at the last date of the last tumor assessment that confirmed that their disease had not progressed. Participants with no tumor assessments after baseline who were alive at the time of clinical cutoff were censored at the date of randomization. Participants who underwent surgical resection with curative intent without prior progression were censored at the date of surgery. PFS was based on tumor assessments made by the investigators according to the RECIST criteria. Non-inferiority analysis that followed the general approach took into account all tumor assessments obtained during the primary study treatment phase, the post-study treatment phase and those obtained during the follow-up phase. Non-inferiority of the XELOX-containing arms compared with the FOLFOX-4- containing arms was investigated.","dispersionType":"95% Confidence Interval","groups":[{"description":"Participants from the initial 2-arm part and the 2x2 factorial part of the study including the following groups -\n\n1.
