^{^a}

Estimated quality of life summary score of a female patient, aged 67 years, average time after surgery, no chemotherapy treatment and no supportive care sought for the upper and lower gastrointestinal tract, unspecified gastrointestinal symptoms, fatigue and physical functioning (reference).

^{^b}

Estimated change in quality of life summary score of a female patient, aged 67 years, average time after surgery, no chemotherapy treatment, with an average quality of life score at inclusion, and no supportive care sought for the upper and lower gastrointestinal tract, unspecified gastrointestinal symptoms, fatigue and physical functioning (reference).

^{^c}

Age = (Age − 67 years).

^{^d}

Time after surgery = (Time after surgery – 7 months).

^{^e}

Quality of life at inclusion = (Quality of life score – 81.9).

^{^f}

The model includes an interaction term between the average quality of life score at inclusion and treatment with chemotherapy.

p < 0.05.
