“…In addition, while older patients (especially those ≥70 years of age) are underrepresented in interventional clinical trials [16][17][18], 29% of patients observed in the FRAME study were ≥70 years of age. Certain baseline characteristics are known to be prognostic factors, such as PS and disease stage [19] and, as reported by the physicians in this study, PS, histopathological/cytological diagnosis as well as age are key factors in the choice of the FLT [12]. Since patients were not randomized to treatment cohorts in FRAME, baseline characteristics including age, gender, PS and stage, varied significantly (p < 0.01) among cohorts and outcomes should not be directly compared among cohorts.…”
