Reducing bias: accounting for the order of co-first authors

J Clin Invest. 2019 Apr 29;129(6):2167-2168. doi: 10.1172/JCI128764.


Reflecting an increasing emphasis on collaborative science, the number of authors on published articles has markedly risen with time. With this trend, we see an increase in papers designating 2 or more co-first authors. To improve transparency in how such designations are made and reduce bias in the assignment of order, the JCI is now requiring an explanation for how the first-author position is determined when shared among contributing authors.
