Participants were divided into three groups: the first 12 received one tablet (200 milligrams) of nevirapine once a week for 12 weeks, the second group of 12 received one tablet twice a week, and the third group of nine took one tablet every other day.

The former has both of the bamboo species that pandas depend on, while the latter only has one of them.

For humans, the 20 amino acids can be divided into two groups: Eleven are made by the human body and are called "nonessential"; the other nine are not made by the body and are called "essential."
