Inclusion of children with developmental disabilities in clinical trials

Our review of the first 100 titles of registered clinical trials of ECD interventions (Appendix 1), and inclusion of children with disabilities, demonstrated that 50% of the trials exclude children with disabilities, 22% of trials target children with disabilities, 3% of trials target children in general and include children with disabilities and 25% of trials do not specify whether children with disabilities are included or excluded.
