Reproducibility discrepancies following reanalysis of raw data for a previously published study on diisononyl phthalate (DINP) in rats.

ABSTRACT: A 2011 publication by Boberg et al. entitled "Reproductive and behavioral effects of diisononyl phthalate (DINP) in perinatally exposed rats" [1] reported statistically significant changes in sperm parameters, testicular histopathology, anogenital distance and retained nipples in developing males. Using the statistical methods as reported by Boberg et al. (2011) [1], we reanalyzed the publically available raw data ([dataset] US EPA (United States Environmental Protection Agency), 2016) [2]. The output of our reanalysis and the discordances with the data as published in Boberg et al. (2011) [1] are highlighted herein. Further discussion of the basis for the replication discordances and the insufficiency of the Boberg et al. (2011) [1] response to address them can be found in a companion letter of correspondence (doi: 10.1016/j.reprotox.2017.03.013.; (Morfeld et al., 2011) [3]).
