Trends in childhood routine immunisation and maternal health service access and utilisation in Sokoto State, Nigeria. A quantitative survey.
Article in Scientific reports, 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
Sokoto State, Nigeria, continues to report some of the lowest maternal, neonatal, and child health (MNCH) indicators nationally. The COVID-19 pandemic further disrupted service delivery in Nigeria, yet its long-term impact on routine immunisation (RI) and maternal health services at the sub-national level in fragile and resource-constrained settings remains underexplored. We conducted a retrospective cohort study using secondary administrative data from 2015 to 2023 to examine the trends in the uptake of the first and third doses of the diphtheria-tetanus-pertussis containing vaccines (DTP-1 and DTP-3), and facility-based deliveries. Dynamic time-series regression models were applied to assess the influence of the COVID-19 period and contextual factors, including climate change, settlement type, and health budgets. DTP-1 coverage and proportion of facility deliveries improved over time. There was a significant increase in facility deliveries during the COVID-19 pandemic (p = 0.019), while DTP-1 coverage declined modestly during the pandemic (p = 0.030). DTP-3 showed no significant change (p = 0.078). Urban residence was positively associated with facility delivery. Lagged dependent variables were strongly significant across the models, indicating path dependency in service utilisation. These findings highlight both resilience and vulnerability within Sokoto’s healthcare system. While maternal services were adapted during the pandemic, immunisation continuity remained fragile. These insights could inform the development of a pandemic-resilient framework for MNCH services in similar settings.
