Hmmm, I suppose opinions can vary, but as I read the report, out of 270 pregnancies included within the trials, 238 pregnancies were so hum-drum that nothing was reported about them.
The article, of course, is chockkers with fear pron, and tries to "sell" the canard that the lack of a report means these pregnancies all ended in fatal results as well - that is, in addition to the 28 pregnancies that were stated to have ended in fatal results.
But, to be quite honest, there is no basis for the fear-pron conclusion the article is trying to draw. The better conclusion to draw is that these pregnancies were not reported further because they reached their natural conclusion - live birth - without any complications.
