Amifostine vs no treatment/placebo

Salivary flow rate (unstimulated) · Patients receiving radiotherapy on its own or in addition to chemotherapy to the head and neck region

It is very uncertain whether amifostine changes salivary flow rate (mg/5 min, unstimulated) compared with no treatment/placebo (very low certainty).
