Additional information

A summary is only available for this report (MOE, 2004) and so it has not been fully evaluated. This study is used as a critical study for the SIDS endpoint and is used in the IUCLID Data Set for Octane-1-thiol (2004). The study has been given a Klimisch score 1 - reliable without restrictions (Klimisch et al, 1997) in the IUCLID Data Set and is here considered as Klimisch 1 until the reference is available as being sponsored by MOE one can consider the study as relevant.
