- Limitations and caveats
Some population groups were underrepresented or not represented (e.g., patients who did not prefer to speak English or Spanish). The study was unable to collect reliable data on web-based dashboard use, limiting the ability to evaluate which digital components of the Greenlight Plus intervention were associated with effectiveness. Anthropometric measures collected during clinical care may be susceptible to measurement error. However, annual training was implemented to minimize errors.

Registered outcomes4
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Child Weight for Length Trajectory | Baseline to 24 months | The primary outcome was child weight for length (kg/m) trajectory over 2 years. Weight and length measurements were obtained during pediatric care visits and abstracted from the medical record. |
| Secondary | Child BMI Z-score Trajectory | Baseline to 24 months | |
| Secondary | Child Weight-for-length Z-score Trajectory | Baseline to 24 months | |
| Secondary | Child Overweight and/or Obesity | at 24 months | Outcome defined by CDC or WHO standards |

Outcomes4
Each outcome the trial posted results for, in ClinicalTrials.gov's words.
| Type | Outcome | Time frame | Population | Units | Measured as |
|---|---|---|---|---|---|
| PRIMARY | Child Weight for Length Trajectory | Baseline to 24 months | Follow-up outcome measures were not obtained for 3 Greenlight Plus participants and 1 Greenlight participant.~NOTE: While the analysis included data from children (n=896) and their parents (n=896), the unit of analysis was the child. Therefore, the number of participants has been reported consistently across the Participant Flow, Baseline Characteristics, and Outcome Measures sections. | kg/m | MEAN |
