Ahmedzai, S., & Brooks, D. (1997). Transdermal fentanyl versus sustained-release oral morphine in cancer pain: Preference, efficacy, and quality of life. The TTS-Fentanyl Comparative Trial Group. Journal of Pain and Symptom Management, 13, 254–261.
To compare transdermal fentanyl and sustained-released morphine in palliative care patients with cancer by measuring efficacy, tolerance, and quality of life (QOL).
