Specifically, the heterogeneity Q statistic was significant ( p < .05); the I 2 value was 59%, exceeding the prespecified threshold of 50% for substantial heterogeneity; and the total Q statistic approached significance (total: χ 2 = 7.36, df = 3, p = .06; within‐design heterogeneity: χ 2 = 7.17, df = 2, p = 0.03, between‐design inconsistency: χ 2 = 0.18, df = 1, p = .67).
