borderline significanceP ≈ .058so close (0.05 < p ≤ 0.1)

In sensitivity analyses excluding AT, ΔDCSA, or sex, acromioplasty consistently increased the risk of stress fracture, with ORs ranging from 2.12 to 2.18 and borderline significance ( P ≈ .058–.067).

did not reach statistical significanceP = .070so close (0.05 < p ≤ 0.1)

Acromioplasty was associated with a higher odds of stress fracture (odds ratio [OR] 2.16, 95% confidence interval [CI] 0.94–4.70), although this did not reach statistical significance ( P = .070), indicating a trend toward increased risk.
