The law makes data collection harder.
Edit: but for those looking for the meat, much of it comes in redefinition of terms. Viability becomes "without application of extraordinary medical measures" instead of "with or without artificial support" and patient's health becomes "including, but not limited to, physical, emotional, psychological, familial, and age." The application of which seems to be interpreted to consider financial and social strain of raising a child. Which is literally every child at every stage in all ages. That's just how they wrote it. Then they punted it to the doctors, forbid much data collection, and picked up the line "it never happens so no, you aren't really allowed to know, there is no point. Discussion over." There's still a federal ban on partial birth abortions.
