key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: see 'Remark'
Remarks:
The reliability is rated 2 because the method of the study is similar to the standard guideline of reference (OECD 115), which describes a procedure designed to evaluate this endpoint, the results were reviewed for reliability and assessed as valid. Study not conducted under GLP conditions.
