The plot lines represent the patient-reported scores on the Trial Outcome Index of the Functional Assessment of Cancer Therapy–Ovary (FACT-O TOI). Scores range from 0 to 100, with higher scores indicating a better quality of life. The estimates of least-squares mean scores were obtained from a fitted mixed model that was adjusted for pre-treatment score (baseline score), chemotherapy received, the country in which the treatment was given, the interval during which no platinum-based chemotherapy was used (platinum-free interval) before recurrence (6 to 12 months vs. >2 months), and the patient’s age at enrollment. Surgery was associated with significantly lower postoperative FACT-O TOI scores. The scores were similar in the two groups at 6 weeks after treatment and at every subsequent assessment.
