For HIV patients with belly fat who responded to tesamorelin, the drug made the subcutaneous fat denser by 3.5 points on a CT scan scale compared to placebo, regardless of changes in fat amount.
Scientific Claim
Tesamorelin increased subcutaneous adipose tissue density by 3.5 Hounsfield Units (95% confidence interval 2.3-4.7) more than placebo in people living with HIV with central adiposity who responded to treatment over 26 weeks, after adjusting for baseline density, area, and area change.
Original Statement
“Adjusted 26-week change**⌘ SAT density (95% CI) 3.5 (2.3, 4.7) p<0.001”

Assessment Explanation
The RCT design allows for causal claims about the specific outcome measured (CT density). The verb 'increased' is appropriate as it directly reflects the measured change.
Evidence from Studies

Tesamorelin improves fat quality independent of changes in fat quantity
The study found that a drug called tesamorelin made the fat under the skin denser and healthier in HIV patients, even without changing how much fat there was — and the numbers in the claim match what the study found.
