Meta-regression analysis showed a marginally significant inverse relationship between cumulative treatment duration and cognitive improvement (β = –0.001, p = 0.055, R 2 = 0.067).

Although a negative trend was observed (β = −0.181), the association did not reach statistical significance ( p = 0.110, R 2 = 0.047), suggesting that course length was not a major source of heterogeneity ( Figure 3D ).
