HIV patients with belly fat who responded to tesamorelin had more lean muscle mass in all four trunk muscles, with increases between 0.64 and 1.08 cm² compared to placebo after 26 weeks.
Scientific Claim
In HIV-positive adults with abdominal obesity who responded to tesamorelin treatment (≥8% visceral adipose tissue reduction), tesamorelin was associated with a 0.64 to 1.08 cm² greater increase in lean muscle area across all four trunk muscle groups compared to placebo after 26 weeks.
Original Statement
“in the lean muscle area of all four truncal muscle groups (0.64-1.08 centimeters2; p<0.005)”
Evidence Quality Assessment
Claim Status
appropriately stated
Study Design Support
Design supports claim
Appropriate Language Strength
association
Can only show association/correlation
Assessment Explanation
The study design (RCT) supports causal claims within the specific population, but the recommended verb strength is association to reflect the specific responder subgroup and avoid overgeneralization. The claim uses 'associated with' appropriately.
