I think our posts are crossing each other at sea.  I have one long post
where I quoted the same article as your first one, and then I had one
where people were arguing with each other about the statistical analysis
of the studies and whether anything useful was shown.

Shirley was asserting that it was well-established that folate causes
the spontaneous abortion of NTD babies.  Barbara and I were shuffling
around in the research and questioning whether it was really
well-established or indeed, established at all.  I haven't pursued it
further in the last hour but I stand by the reading that I did that
suggests that indeed, spontaneous abortion of NTD babies in the presence
of folate is not even somewhat established, let alone well-established.
