EWG Primodos review criticised for ‘not assessing risks properly’

Sky News’ Exclusive, 4 Apr 2019

“Somebody, somewhere, has performed a meta-analysis.
At some point, there was a decision not to include that in the EWG report.”

Oxford University professor Carl Heneghan has told Sky News the evidence against the pregnancy drug Primodos suggests a significant link between it and birth deformities (see below).

On 23 April 2019, during the Westminster Hall debate on the Expert Working Group report on hormone pregnancy tests, some MPs also questioned the methodology used and asked why not use meta-analysis to assess primodos evidence ? Some others clarified the difference between correlation vs causation (in ref to primodos link to births defects), or said : with pharma funding the MHRA, can the EWG report be fully independent ?
