1 · What the graph read from it

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.

2 · The registry

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

This study investigates how armed conflict influenced paediatric vaccination uptake in Nigeria. Combining Demographic and Health Survey data with detailed conflict event information, we examine the relationship between the intensity of reported conflicts near children's residences and their vaccination probabilities. Our findings reveal that a 1 SD increase in conflict intensity reduced vaccination rates by 0.73-1.80 percentage points (between 2.10% and 4.60% of the mean). The results suggest that beyond disrupting healthcare infrastructure, conflict may affect vaccination rates through demand-side effects, where heightened security risks lead parents to deprioritise preventative health investments. These findings contribute to understanding vaccination challenges in conflict zones and inform targeted immunisation strategies.
