Geographic disparities and determinants of DTP3 vaccination coverage among children aged 0-59 months in Somalia: a multilevel analysis.
Article in Conflict and health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundIn Somalia, a fragile state characterized by protracted conflict and fragmented health governance, childhood immunization remains a critical challenge. The third dose of the Diphtheria-Tetanus-Pertussis (DTP3) vaccine serves as a key indicator of health system performance and retention. This study aimed to identify structural and individual-level determinants of DTP3 coverage to understand the inequities in this humanitarian setting.
methodsA cross-sectional analysis was conducted using data from the 2020 Somali Health and Demographic Survey (SHDS). A total sample of 1,268 children was analyzed. Multilevel mixed-effects logistic regression models were fitted to account for the hierarchical structure of the data (children nested within communities). Fixed effects were reported as adjusted odds ratios (aOR) with 95% confidence intervals (CI).
resultsThe overall prevalence of DTP3 vaccination coverage was 39.51% [95% CI: 36.85-42.23]. At the individual level, higher maternal education (Secondary vs. no education: aOR = 1.83; 95% CI: 1.07-3.12), wealth status (Rich vs. poor: aOR = 2.41; 95% CI: 1.53-3.79), and antenatal care (ANC) attendance (3-4 visits vs. zero visits: aOR = 2.19; 95% CI: 1.43-3.36) were significantly associated with higher odds of vaccination. Older children had higher odds of vaccination compared to infants, suggesting delayed rather than timely uptake. At the community level, children in rural (aOR = 0.40; 95% CI: 0.28-0.57) and urban (aOR = 0.64; 95% CI: 0.45-0.91) areas had lower odds of vaccination compared to those in nomadic communities. Significant regional disparities were also observed.
conclusionsDTP3 coverage in Somalia is critically below the WHO 90% target. Vaccination status is shaped by a complex interplay of socioeconomic status, maternal healthcare utilization, and geographic location. Policy interventions must urgently address the 'urban penalty' identified in this study, where settled urban-poor populations now face lower odds of vaccination than nomadic groups targeted by mobile outreach.
