Progressive Disease was defined as at least a 20% increase in the sum of LD of target lesions, taking as reference the smallest sum LD recorded since the treatment started or the appearance of one or more new lesions. PFS was defined as time from randomization to the date of documented disease progression or death, whichever occurred first. Participants without progression were censored at the date of last tumor assessment where non progression was documented. If a participant receives a second anti-cancer therapy without prior documentation of disease progression, the participant was censored at the date of last tumor assessment before starting new chemotherapy.","dispersionType":"95% Confidence Interval","groups":[{"description":"Participants received either pemetrexed 500 mg/m\\^2 every 21 days until disease progression, unacceptable toxicity or death or docetaxel 75 mg/m\\^2 every 3 weeks until disease progression, unacceptable toxicity or death.
