Carrying out the research during that time afforded researchers the opportunity to have a more extensive sample base than if the research had been conducted today. The 25-year study took into consideration the relationship and comparisons between the paraxanthine (80% caffeine intake is broken down into paraxanthine) levels, children’s cognitive skills and behavioral pattern.

With blood sample from 2,197 pregnant women, the study concludes that
