When analyzed by BAR tertiles, patients in the highest tertile (T3: 4.255–10) exhibited a more pronounced reduction in MoCA scores (β = −0.44, 95% CI: −0.81 to −0.07, p = 0.019) compared to the lowest tertile (T1: 1.489–3.265), while the middle tertile (T2: 3.265–4.255) showed a marginal trend ( β = −0.34, 95% CI: −0.68 to 0.01, p = 0.06).
