Publication bias and egger’s test for the EEG-NFT on WM (A) and EM (B). The black line represents the null hypothesis that the study-specific effect sizes do not differ from the respective comparison-specific pooled effect estimates. The blue and green lines respectively represent the regression line on WM and EM. The different colors correspond to different comparisons. [WM (A = AC, B = alpha + theta, C = alpha + WMT, D = alpha, E = gamma, F = LB, G = PC, H = SMR, I = sham + WMT, J = sham, K = SC, L = theta/alpha, M = theta, N = UA + PC, O = UA + WMT, and P = UA); EM (A = AC, B = alpha, C = beta/theta, D = beta, E = gamma, F = LA/UA, G = PC, H = SMR, I = sham, J = SC, K = theta/LB, L = theta, and M = UA)]. conf., confidence; MSE, mean standard error; Std_eff, standard effects; Std. err., standard error
