Can a visual self-learning tool improve immunisation awareness? Evidence from a quasi-experimental pilot study in Madhya Pradesh, India.
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
introductionImmunisation coverage in low- and middle-income countries continues to face challenges due to persistent gaps in vaccination schedule knowledge among caregivers and health workers. The Routine Immunisation Wheel was developed as a low-cost visual tool to complement existing systems like Mother Child Protection (MCP) cards and community healthcare worker visits in Madhya Pradesh, India. This pilot study evaluates the tool’s effectiveness on improving knowledge and awareness among caregivers and frontline workers (FLWs), as well as its potential for scaling within routine immunisation programs. METHODOLOGY: Using a mixed-methods approach, we conducted a quasi-experimental pilot comparing intervention and control districts with 384 caregivers per arm and more than 60 FLWs (vaccinators/Auxiliary Nurse Midwife (ANMs), mobilizers Accredited Social Health Activists (ASHAs) and Anganwadi Workers (AWWs). Statistical analysis included descriptive statistics for demographics, mean scores with 95% confidence intervals for knowledge domains, independent samples t-tests for group comparisons, chi-square tests for proportions, and thematic analysis of qualitative feedback.
resultsAt endline, caregiver knowledge scores in the intervention district were higher than at baseline for immunisation schedule (mean: 53.7% vs. 35.6%, p < 0.05), immunisation benefits (mean: 87.4% vs. 62.5%, p < 0.05), and session site awareness (95.1% vs. 89.8%, p < 0.05). When compared with the control district at endline, the intervention district had, on average, higher scores for immunisation schedule knowledge, immunisation benefits and session site awareness (all p < 0.05). The tool demonstrated high utility among health workers, with 100% adoption by ANMs for due listing and counselling.
conclusionThe routine immunisation wheel effectively addresses critical knowledge gaps in routine immunisation through its dual functionality as both caregiver reminder and healthcare worker job aid. These results highlight its potential for integration into broader immunisation strategies, especially in low-literacy, resource-limited settings.
