Adults with type 2 diabetes who did aerobic exercise had about 0.6 lower insulin resistance scores than those who didn't exercise, after 12 weeks.
Scientific Claim
Aerobic exercise was associated with a 0.61 unit greater reduction in HOMA-IR compared to no structured exercise in adults with type 2 diabetes and BMI ≥23 kg/m² after 12 weeks.
Original Statement
“HOMA-IR Group A: 2.80 (1.08) to 2.17 (0.91); Group 2: 2.78 (1.21) to 2.76 (1.06). Within-group change for Group A: Z = -3.44, p < 0.001; Group 2: Z = -0.22, p = 0.826. Overall comparison of change: F = 11.04, p < 0.001.”

Can only show association/correlation
Assessment Explanation
The study design is quasi-experimental, which can only show association, not causation. The claim uses 'associated with' correctly.
