The problem
Intervention: Community-based interventions including mobile vaccination clinics, community health education, digital reminder systems, and local stakeholder engagement
Who it was tested with: 4,500 children aged 0-14 years in 25 underserved communities in India.
The same group is measured before the intervention and again afterwards, with a baseline and an endline and sometimes a midline. Change is visible, but other causes cannot be ruled out.
"A longitudinal community intervention study in 25 underserved communities in 2022-2025 with 4,500 children aged 0-14 years. Intervention strategies involved community health education, mobile vaccination clinics, digital reminder systems, and local stakeholder engagement." The design tracks the same population over time with multiple measurement points, but without a comparison group to control for external factors.
The study lacks a comparison or control group to isolate the intervention effect from secular trends. The document does not specify whether all four intervention components were implemented simultaneously or sequentially, or whether communities received different combinations of interventions.
