Clinical Studies

Quality of Trials - Infertility

Most of the clinical trials of infertility have a low risk of bias due to adequate sequence generation; the methods of dividing participants into different groups were clearly described. Although some trials noted the methods for blinding, many had unclear descriptions of blinding and allocation concealment. Among these studies, the one with the lowest risk of bias was performed by Wu (Wu, et al. 2006). In that study, although the risk of selective reporting is unknown, all other biases were clearly described and of low risk. References: Ren X. 2002.
