Analysis revealed that among patients receiving the highest dose of tirzepatide treatment, 73.9% achieved the trial's primary endpoint, with NASH symptoms resolved and liver fibrosis not worsening after 1 year of treatment [10]
The researchers behind it come from leading research centres, and the fact that it has been peer-reviewed and published in a reputable journal indicates that it is a serious piece of work
