Socio-demographic factors associated with incomplete vaccination or non-vaccination among children aged 12-23 months in Sierra Leone.
Article in BMC public health, 2025. 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
backgroundChildhood vaccination coverage in Sierra Leone remains unsatisfactory despite multiple efforts made by health authorities to enhance collective immunity of the population, especially for children aged 12 to 23 months. This study aimed at identifying the factors associated with incomplete vaccination or non-vaccination among children aged 12 to 23 months in Sierra Leone in 2019.
methodsThis was a cross-sectional study that used the 2019 Sierra Leone Demographic and Health Survey data. Descriptive statistics was performed to describe the sample, ascending hierarchical classification following a multiple correspondence analysis was employed to establish the profile of children with incomplete vaccination or non-vaccination status, and a binary logistic regression was used to identify the factors associated with incomplete vaccination or non-vaccination.
resultsOf the 966 children aged 12 to 23 months involved in the study, 42.9% (95% CI[39.2; 46.6]) were incompletely vaccinated or unvaccinated, of which, 43.5% (95% CI[37.9; 49]) among male children and 42.4% (95% CI[37.3; 47.4]) among their female counterparts. The Northern (AOR 1.683, 95% CI[1.131; 2.503]) and the North Western (AOR 1.847, 95% CI[1.208; 2.825]) survey regions, delivery in a place other than a health facility (AOR 1.404, 95% CI[1.001; 2.042]), the mother's age group 35 to 49 years (AOR 0.437, 95% CI[0.251; 0.762]) and the child's birth order 7th or higher (AOR 2.640, 95% CI[1.452; 4.800]) turned out to be significant factors of incomplete vaccination or non-vaccination.
conclusionIncomplete vaccination or non-vaccination among children was high in Sierra Leone in 2019. In order to increase childhood vaccine uptake, we recommend the development of initiatives geared towards optimizing facility-based service delivery, intensifying health education focusing more on vaccination, enhancing community engagement, addressing barriers to vaccine access, establishing and ensuring proper functioning of immunization defaulter tracking systems.
