10 points Researchers studied 208 infants whose brains were temporarily deprived of
oxygen due to complications at birth. When researchers detected oxygen deprivation, they randomly
assigned babies to either usual care or to a whole-body cooling group. The goal was to see whether
reducing body temperature for three days after birth increased the rate of survival without brain
damage.
