Re: Bydreon study

Bydureon treatment produced an average weight loss of 4.5 pounds (2 kg), which was statistically significantly greater than the average 1.7 pounds (0.8 kg) patients lost with Januvia and the average 3.3 pounds (1.5 kg) patients gained with Actos. But patients receiving metformin experienced an average weight loss of 4.4 pounds (2 kg).

Are these weight-loss numbers averages or medians?
