Notes from the review of this manuscript
In order to receive a high rating, randomized controlled trials (RCTs) with low attrition must control for race/ethnicity, socioeconomic status (SES), and, if applicable, baseline outcomes if statistically significant differences exist between treatment and control groups. In this case, there were no significant differences in terms of race/ethnicity, but we had insufficient information to assess baseline equivalence on SES because the only SES measure collected at baseline was maternal education. HomVEE prefers to see equivalence on income, earnings, or poverty levels according to federal thresholds, but also considers other measures of SES (that is, maternal education, employment, and Aid to Families with Dependent Children/Temporary Assistance for Needy Families or food stamps receipt), if at least two such alternative measures of SES are provided.

Study Participants
Participating mothers were recruited from the postpartum unit of a hospital in Philadelphia and randomized into treatment and control groups. Of the 650 mothers who met eligibility criteria, 618 were invited to participate (32 were not invited, largely due to being discharged early from the hospital). The 302 mothers who consented to study participation were randomized to the treatment (n = 152) and control (n = 150) groups. All mothers lived in zip codes with high rates of poverty and each had just given birth to a singleton that weighed at least 2,500 grams and did not appear to have any genetic or developmental disorders. The study notes that most of the mothers were African American but does not provide statistics on the racial composition of the sample. The mothers had completed 12 years of schooling. No additional baseline data on socioeconomic status are specified. Participants were followed from birth until 33-months of age: telephone interviews were conducted with the mothers every four months, in-person assessments of children were completed at 18 and 33 months, and mothers were assessed and interviewed at 33 months.
Setting
The study was conducted in a high-poverty area of Philadelphia.
Intervention condition
Note: Navigate to the model page for more information about the home visiting model. See the source manuscript for more information about how the model was implemented in this study.
Comparison Conditions
The comparison group members received information booklets on child/family services on enrollment and details on transportation for the 33-month child evaluation. They also received follow-up telephone calls every four months to maintain up-to-date contact information.
