From an e-mail conversation with an employee of Cochrane Australia about this claim:

Happy to give some background to this.

Cochrane Australia was contracted by NHMRC as technical advisors to provide a methodological assessment of the NHMRC Homeopathy Review (a review of the evidence that was undertaken by a third party). The statement quoted below (with vital text omitted) comes from our technical report. It’s our understanding that our report was obtained through an FOI request by Brauer; it’s not publicly available.

We addressed this issue last year when we were contacted by The Guardian, see https://www.theguardian.com/lifeandstyle/2017/jun/30/homeopathy-company-investigated-over-ebook-advocating-treatment-of-babies.

The statement from the report is a technical comment on generic wording used in the Review. In our report we repeatedly agree with the conclusions of the NHMRC Homeopathy Review, as reiterated in the quote from The Guardian article. The deletion of text by Brauer is misleading. (We’re essentially making the general point that you can have reliable evidence that there is no evidence of effectiveness.)
