"Few studies used a placebo as a control. Instead ‘positive effect drugs’ were used. Most Chinese trialists select the control drugs by a rule of ‘the effect was commonly acknowledged’. This rule may lead to conflict of interest bias, and subjective over- or under-estimate of the effect of the trial preparation depending on the aim of the study. If a preparation was tested as the intervention, it had a high rate of effectiveness; if used as a control drug by another author, it may have had a much lower rate of effectiveness. Therefore, it is difficult to determine the efficacy of the intervention drug. Where the intervention drug was equal in efficacy to the control drug, no conclusion could be made."
