Before treatment, the fat under the skin looked just as healthy on scans in both the drug and placebo groups — so any changes later were caused by the drug.
Scientific Claim
In people living with HIV (PWH) with central adiposity, baseline subcutaneous adipose tissue (SAT) density was similar between tesamorelin responders and placebo groups (−94 HU vs. −95 HU, P = 0.29), indicating no pre-existing differences in fat quality.
Original Statement
“Baseline characteristics were similar across arms, including VAT (−91 HU both arms, P = 0.80) and SAT density (−94 HU tesamorelin, −95 HU placebo, P = 0.29).”

Tesamorelin improves fat quality independent of changes in fat quantity
Before starting the treatment, both groups had similar types of fat under the skin, so any changes later were likely due to the medicine, not pre-existing differences.
