Uterine weight: It was noted that tissues were removed, cleaned, and weighed (+ for methods). Blinding was not reported (NR for blinding).

Uterine histopathology: Standard H&E methods were used to prepare slides. No information is provided on how analysis was conducted (+ for methods). Blinding was not reported (NR for blinding).

Although blinding was not specified, it was noted in Kendig et al., 2012 a similar study by the same group during the same time period that all measurements and endpoints were made by an observer blinded to the treatment, litter, and sex where appropriate. Therefore, it is assumed that blinding of outcome was also part of this study. Therefore, weight and histopathology would have an overall rating of +.
