Conflicting findings in environmental epidemiology have lengthy stalled consensus at the well being results of poisonous chemical substances. A brand new find out about through Columbia College Mailman College of Public Well being printed within the American Magazine of Epidemiology means that one primary explanation why for those inconsistencies could also be the restricted publicity levels in person research—resulting in underpowered effects and unclear conclusions.
Researchers used simulated knowledge to inspect how neatly person and pooled research can determine dose-response relationships between chemical publicity and well being results. Their findings level to a transparent answer: pooling knowledge throughout research must be prioritized, even if confounding variables range between cohorts.
“Underpowered studies—especially those with narrow exposure ranges—may produce misleading results about whether and how a chemical affects human health,” mentioned lead writer Eva Siegel, Ph.D. within the Division of Environmental Well being Sciences. “Our simulations show that combining data across multiple cohorts is a natural and necessary step to strengthen conclusions in environmental health research.”
