  1. * indicates statistical significance (p < 0.05). The adjusted model controlled for ΔGA and ΔBW between matched pairs. ΔGA: OR = 1.422 (95% CI: 0.995–2.032), p = 0.054; ΔBW: OR = 0.151 (95% CI: 0.027–0.839), p = 0.030. Model fit improved significantly after adjustment (Likelihood ratio test: χ² = 6.7, df = 2, p = 0.035).
