Socioeconomic inequalities in immunisation of 12-23 months old children in Malawi: a decomposition analysis.

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
Background: Given the benefits of the Expanded Program on Immunisation (EPI) to Malawians' health and, consequently, Malawi's economic development, coverage and equity in immunisation are necessary to track. In the 2019-20 Malawi Multiple Indicator Cluster Survey (MICS), immunisation coverage of basic vaccines among 12-23-month-old children was at 72%. However, disaggregated immunisation coverage in some groups of children was below or above 72%. The disparities compelled the need to investigate the extent of socioeconomic inequalities drivers in child immunisation in Malawi. Study design: This study uses secondary data sets from three of Malawi's national representative cross-sectional surveys: the Malawi MICS 2013-14, the Malawi MICS 2019-20 and the Malawi Service Provision Assessment (MSPA) 2013-14. The MSPA 2013-14 was used to estimate the shortest distance between a MICS 2019-20 cluster and a facility offering immunisation services. Methods: The study utilized the concentration index to measure socioeconomic inequality and the Wagstaff decomposition to measure the marginal contributions of socioeconomic factors to inequality. Results: The study found no socioeconomic inequality in 2013, but pro-rich inequalities existed in 2019 (0.065 for basic immunisation, 0.09 for age-appropriate immunisation), statistically significant at Conclusion: The results call for interventions that improve affordability and accessibility of vaccines and interventions that educate caregivers of the benefits of child immunisation to ensure equity. The results, therefore, suggest that to improve equality in health outcomes, the Government of Malawi needs to embrace wider policies that do not only address the consumption of healthcare services but also policies that affect socioeconomic determinants of health.
