The five randomised clinical trials were parallel group trials published as full articles. Three of the five included trials had three arms which were phyllanthus, antiviral drugs, and a combination of phyllanthus and antiviral drugs (Huang 2004; Ouyang 1999; Zhu 2005). The data from the two arms comparing phyllanthus alone versus antiviral drug alone were included in this review. Two hundred and ninety patients randomly allocated to phyllanthus versus antiviral drugs were included into analyses of our review.
