In Reply We thank Cristea et al for their careful reading of our meta-analysis of school-based interventions for bullying prevention.1 Cristea et al state that 85% of the included trials evaluated universal prevention and should have ideally included a measure of risk reduction, such as incident or recurrent cases. However, more than 85% of those studies did not report such measures. Although our comprehensive approach is subject to some limitations, the exclusion of such studies would substantially limit the generalizability of our findings.
