The introduction of group antenatal care in northern Nigeria: an implementation research study analysing changes in service use.
Article in BMJ global 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
introductionWith one of the highest rates of maternal mortality in the world, improving antenatal care for the poorest communities is a high priority in Nigeria. In 2022, Project HOPE partnered with the Nigerian Ministry of Health to implement group antenatal care, a WHO-recommended health system strengthening intervention for improving pregnancy outcomes in Niger State.
methodsThe project trained 300 health workers and established group antenatal care in 150 health facilities. Training and initiation was staggered over September, October and November of 2022. Over 17 000 women participated in 1054 antenatal care groups from September 2022 to March 2023. We carried out an implementation research study to examine service utilisation rates and explore contributing factors within the project. Using an interrupted time series analysis, we examined project effects on antenatal contacts, facility births, live births, malaria positivity, postpartum contraception and postnatal care.
resultsThe analysis found statistically significant increases in first and fourth antenatal visits, facility births and live births following the intervention.
conclusionDespite significant challenges, including a shortened implementation period, the project increased service use. We assert that health system approaches were key influencing factors, such as the use of local master trainers, broad stakeholder engagement, strong monitoring and evaluation and the inclusion of the group antenatal care model in national guidelines. Noted challenges included inadequate skilled birth attendants and lack of antenatal care commodities, though stop gap measures addressed certain supply issues such as a lack of blood pressure cuffs.
