Targeted assessment of prevalence of zero-dose and under-immunised children in Bangladesh.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionGavi, the Vaccine Alliance and the Global Immunisation Agenda 2030 have intensified their emphasis on equity, with the intent of reaching zero-dose (ZD-missing the first dose of pentavalent) and under-immunised (UI-missing the third dose of pentavalent) children and their communities. In Bangladesh, inequities in immunisation coverage continue and a country learning hub is supporting the Expanded Programme on Immunisation (EPI) with implementation research on how to identify and reach these vulnerable and underserved communities. We report on an assessment of the prevalence of ZD and UI children, and of potential reasons.
methodsThis cross-sectional household survey was conducted in 12 rural and urban subdistricts, purposefully selected from diverse socio-ecological zones: haor (wetlands), hills, coastal, char (silty lands), plain land and urban slums. We interviewed 12 756 caregivers of children aged 4.5-23 months. Households were selected using cluster sampling methodology. The data were collected from September to December 2023. We used χ
resultsWe found that 1.9% of children were ZD and 11.6% were UI. The highest percentage of ZD/UI was in haor areas (21.3%: 2.6% ZD and 18.7% UI). Findings from logistic regression show that children residing in haor (OR 2.0; 95% CI 1.2 to 3.5), coastal (OR 2.1; 95% CI 1.2 to 3.6) and urban slum areas (OR 2.8; 95% CI 1.4 to 5.6) were approximately 2~3 times more likely to be ZD compared with children living in plain areas. Female children were 1.4 times more likely to be ZD than were male children (OR 1.4; 95% CI 1.1 to 1.8). Commonly mentioned reasons for non-vaccination were childhood illness (all areas) and busy schedule of caregivers (char areas).
conclusionZD and UI children are spread throughout the country, with higher ZD in haor, urban slum and coastal areas. Children who are female and those residing in households located distant from the EPI centre are more vulnerable to becoming ZD or UI. Our study findings provide insight on children of specific areas and gender who require greater attention from the policymakers and EPI managers to design programmes to reduce the number of ZD and UI children and thus improve equity in immunisation coverage.
