Notes from the review of this manuscript
The data on Nurse Family Partnership (NFP) and comparison group members were extracted from different datasets that used different data collection procedures (NFP program data versus national WIC data) and different data collection periods. The NFP data includes clients who participated in the program between 2008 and 2012, whereas the comparison group data reflects clients in only 2008, 2010, and 2012. Data collection method and year is confounded with study group.
