[HTML][HTML] Evaluation of excess significance bias in animal studies of neurological diseases

KK Tsilidis, OA Panagiotou, ES Sena, E Aretouli… - PLoS Biol, 2013 - journals.plos.org
Abstract Animal studies generate valuable hypotheses that lead to the conduct of preventive
or therapeutic clinical trials. We assessed whether there is evidence for excess statistical
significance in results of animal studies on neurological disorders, suggesting biases. We ...
