It's the comment he made about how how he wrote the report, though.
" ....and said it was written with knowledge of previous babies in this case."
That tends to suggest that the previous babies he looked at throughout this case might be having some bearing, possibly one which brings him to the same conclusion, on this one. Clearly it is in his mind as he said it was.
Would he have arrived at the same conclusions had he not examined the other cases? That is a pertinent question to ask, surely?
