An update on Lab and Study Protocols at PLOS ONE Emily Chenette, Editor-in-Chief, PLOS ONE PLOS empowers researchers to transform science by offering more options for credit, transparency and choice. The launch of Lab Protocols and Study Protocols in PLOS ONE earlier this year supported this crucial goal by bringing reproducibility and transparency to research, and enabling those who contributed to study design to receive credit for their contributions. Today, we’re delighted to share the news that two Study Protocols have now been published in PLOS ONE. The first, by Satoru Joshita and colleagues, describes a protocol for studying the prevalence and etiology of portopulmonary hypertension in a cohort of Japanese people with chronic liver disease.
