FIGURE 4

Kaplan–Meier estimate for the probability of survival in elderly patients (≥70 years of age) exposed to all three major drugs (capecitabine, oxaliplatin, irinotecan), to just one doublet, or to capecitabine alone, or receiving only best supportive care (BSC). Exposure to the three drugs was superior to exposure to capecitabine alone (log-rank p = 0.004) and to BSC alone (log-rank p < 0.001), but not to exposure to just one doublet (log-rank p = 0.403). OS = overall survival; CI = confidence interval; HR = hazard ratio.
