an increasing trendp < 0.001
For the T‐MoCA, the model examining the piecewise linear trend with knot at wave 3 (Model 0) showed an increasing trend in T‐MoCA before the knot (slope = 0.33 points per annual visit, SE = 0.07, p < 0.001), followed by the slope being reduced by 0.61 (SE = 0.15, p < 0.001) after the knot, resulting in a decreasing trend (slope = −0.27, SE = 0.11, p = 0.010).
