Figure 2 P300 latency and amplitude changes. A: P300 latency change; B: P300 amplitude change. Intra-group comparison before and after intervention: ^bP < 0.01 vs baseline; ^cP < 0.01 vs 3 mo. Comparison between experimental group and control group at different time points: ^dP < 0.05, ^eP < 0.01, experimental group vs control group at baseline/3 mo/6 mo.
