EXPRESSION OF CONCERN: Insulin-Like Growth Factor Binding Protein-1 (Actim PROM test) for Detection of Premature Rupture of Fetal Membranes

Abstract

EXPRESSION OF CONCERN: I. A. Abdelazim, “ Insulin-Like Growth Factor Binding Protein-1 (Actim PROM test) for Detection of Premature Rupture of Fetal Membranes,” Journal of Obstetrics and Gynaecology Research 40, no. 4 (2014): 961–967, https://doi.org/10.1111/jog.12296.

This Expression of Concern is for the above article, published online on 26 February 2014 in Wiley Online Library (wileyonlinelibrary.com), and has been issued by agreement between the journal Editor-in-Chief, Hiroaki Kajiyama; Japan Society of Obstetrics and Gynecology; and John Wiley & Sons, Australia, Ltd. The Expression of Concern has been agreed following concerns raised by a third party regarding the study data presented in Tables 1 and 2. The Group II control data in Table 1 and the IGFBP-1 (Actim PROM test), Ferning test and Nitrazine test data presented in Table 2 are identical to another study published earlier by one of the same authors. The author explained that data from the two studies were combined for comparison purposes. However, this was not explicitly stated in the article and the previously published article was not referenced. Furthermore, the author was unable to provide any original data due to the length of time that has elapsed since publication. Therefore, the journal has decided to issue an Expression of Concern to inform and alert the readers.
