Subnational trends and inequalities of under-immunisation and zero-dose among children aged 12-23 months in Uganda: a national population-based cross-sectional study.

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
objectiveDespite the Global Vaccine Action Plan's goal of at least 90% vaccine coverage for all children, Uganda has made limited progress in vaccination over the past decade. The objective of this study was to examine the subnational trends in the prevalence and inequalities in under-immunisation and zero-dose among children aged 12-23 months in Uganda. STUDY
designA retrospective national cross-sectional study.
settingUganda
participantsUganda Demographic and Health Survey secondary data of only children aged 12-23 months. The samples selected for analyses were 1507 in 2006, 1409 in 2011 and 2650 children in 2016. OUTCOME MEASURE: The primary outcomes were under-immunisation and zero-dose vaccination.Absolute and relative inequality measures were used in the analysis.
resultsFrom 2006 to 2016, the under-vaccination rate decreased by 21%, but remained high at 40.8%. The zero-dose vaccination rate dropped by 82%, affecting 1.2% of children in 2016. Subnational inequalities in under-vaccination increased over time with widening gaps between regions. While inequalities across wealth quintiles, maternal education levels and places of residence narrowed, children of mothers with lower education levels continued to have the highest under-vaccination rates. The rural-urban gap for zero-dose vaccination remained unchanged, with rural children disproportionately impacted.
conclusionWhile some progress was made in reducing under-vaccination rates in Uganda within the study period, no region achieved an under-vaccination rate below 20%. This indicates significant challenges in reaching the Sustainable Development Goal target of at least 80% immunisation coverage. Targeted interventions are necessary to improve healthcare access, enhance public health communication and strengthen the health system, particularly in underserved communities and among vulnerable populations.
