The Nulliparous Pregnancy Outcomes Study: Monitoring Mothers-to-Be (nuMoM2b), which began in 2010, studies pregnant women who will be delivering for the first time (nulliparous women).

Data dictionary management with Spout

Spout is an open-source Ruby tool that helps the National Sleep Research Resource team curate, manage, and version-control data dictionaries that describe underlying datasets on the site. These data dictionaries provide metadata about the variables (columns) within a dataset. A well-defined data dictionary is an essential tool for researchers who want to understand and analyze a given dataset. The NSRR team started development on Spout in 2013. Version 1.0.0 was released on February 1, 2019. Keep reading

Susan recently retired after spending more than 20 years with the Boston Sleep Reading Center group. Susan stewarded the Sleep Heart Health Study, our most popular dataset, from data collection all the way until its posting on the NSRR. Keep reading
