Due to the extensive number of variables needed to be considered there is also the problem of lack of baseline data that can be used for comparative analysis of studies undertaken. There are different factors covered in the study such as the causes of developmental disabilities, challenges in the research process, clinical study of toxic elements known to affect the neurodevelopment such as lead, mercury, manganese, polychlorinated biphenyls, flame retardants, pesticides, nicotine, and alcohol and other solvents.
Upon analysis of the article by Schettler, it can be considered that the study is more of a library based research since the data are presented on a textual manner.
