Question

Newborn Brain DamageResearchers 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.What is the purpose of including the "usual care" treatment in the experiment?A, To provide a baseline for judging the survival rates of infants who received whole-body coolingB, To control for the placebo effect and keep it from confounding the resultsC, To create similar treatment groups so that a cause-and-effect relationship can be established

Answer 1

A, To provide a baseline for judging the survival rates of infants who received whole-body cooling

Step-by-step explanation:

The researchers included the usual care treatment in the experiment so that they could compare the results of this treatment with the results of the whole body cooling treatment. With this comparison, the researchers could assess whether cooling treatment had more positive effects on babies than usual care. Therefore, we can conclude that the investigators included "usual care" treatment to provide a baseline for judging the survival rates of infants who received whole-body cooling.
