Data are presented as mean ± SD. Reliable change index = to quantify change in cognitive performance over time the reliable change index was computed from baseline and follow‐up data by the following formula: ((Xfollow‐up−Xbaseline)−(mean‐controls follow‐up−mean‐controls baseline))/standard deviation delta‐score controls. Bold values are statistically significant results (P < 0.05).
