A meta-analysis of 28 trials found that Mounjaro tends to reduce body weight more than semaglutide, ranging from 11 lbs to 21 lbs with tirzepatide, compared to 6 lbs to 11 lbs for semaglutide
The analysis was conducted from the perspective of Chinese payers, and a lifetime horizon was used
Subsequent subregion analyses showed that the ventral tegmental area as well as subregions of the amygdala displayed enhanced activity patterns after GLP-1MK-801 treatment (Extended Data Fig
