The Editors of Obstetrics & Gynecology are retracting “Sildenafil Citrate Therapy for Oligohydramnios: A Randomized Controlled Trial,” by Maher et al,1 originally published in the journal's April 2017 issue (http://dx.doi.org/10.1097/AOG.0000000000001928). This retraction notice updates the Expression of Concern published in the journal's August 2019 issue.2

The journal engaged an expert to conduct an independent statistical review of the data. This analysis was conducted concurrent with attempts by the journal to correspond with the authors' institution (Menoufia University). The independent statistical reviewer concluded that it is unlikely that the data are genuine and further noted that patterns and correlations in the data set are very clearly compatible with the invention of data.

Although the Editors understand that Menoufia University intends to investigate, in light of the passage of time since publication of the Expression of Concern (approximately 8 months), during which we have received no information to help assuage the concern, and the conclusions of the independent statistical reviewer, the journal is retracting “Sildenafil Citrate Therapy for Oligohydramnios: A Randomized Controlled Trial.” This retraction is being published online ahead of print on March 9, 2020.
