This is something I've seen called out before when these comparisons are trotted out but I don't see it mentioned in this article.
Here is a blurb I found quickly (from https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4856058/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4856058/)
> First, many countries also have reporting requirements related to birth weight and may not report infants under 500 grams as live births (MacDorman and Mathews 2009). Second, the presence of assisted reproductive technologies has increased the frequency of multiple births, which have higher mortality rates.
