High rating applies to most outcomes. Medical record outcomes receive a low rating because of high attrition and failure to demonstrate baseline equivalence.

Study characteristics
Study participants Participants (infants and their families) were recruited from local hospitals and clinics in the Denver, Colorado, area and assigned randomly to either the intervention or the comparison group. Initially 181 infants were randomly assigned, 90 to the treatment group and 91 to the comparison group. At baseline, the study groups were split among European Americans (22 percent treatment, 21 percent control), African American (23 percent treatment, 22 percent control), U.S.-born Hispanic (33 percent treatment, 31 percent control) and foreign-born Hispanic (22 percent treatment, 20 percent control). Approximately half of each group had incomes less than $12,000 per year. Participants were followed for one year after baseline data were collected.
Setting The study was conducted in Denver, Colorado.
Intervention services The intervention included home visits conducted by specially trained nurses. The intervention began when infants were from 9 to 24 months old and continued for 12 months. Participants received approximately 15 visits (or telephone calls) by a public health nurse. Each visit lasted an average of 53 minutes.
Comparison conditions Comparison group members received an educational video at the baseline interview that described risk factors for developing asthma and actions that caregivers can take to mediate the risks.
Subgroups examined This field lists subgroups examined in the manuscript (even if they were not replicated in other samples and not reported on the summary page for this model’s report).
