The test for heterogeneity was marginally significant ( I 2 = 33%; τ 2 = 0.0361, p = 0.06) and we opted for the more conservative approach of proceeding with a random effects model, showing a significant ( z = 7.14, p < 0.0001) positive Cohen’s d 0.58, 95% CI ranged from 0.42 to 0.74.

Critically, there was only a significant attention shift effect induced by right, but not left, parietal TMS although the direct statistical comparison between the left and right hemisphere failed to reach significance.
