EA = electroacupuncture; No. = number; RCT = randomized controlled trial; VAS = Visual Analog Scale.

aSee text and the NCI Dictionary for additional information and definition of terms.

bNumber of patients treated plus number of patients control may not equal number of patients enrolled; number of patients enrolled equals number of patients initially recruited/considered by the researchers who conducted a study; number of patients treated equals number of enrolled patients who were given the treatment being studied AND for whom results were reported.

cStrongest evidence reported that the treatment under study has activity or otherwise improves the well-being of cancer patients.

dConcurrent therapy here means the concurrent therapy for the symptoms treated rather than for the cancer.
