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 registryThe 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.

6 · The paper itselfAbstract
In 2024, WHO recommended pentavalent meningococcal conjugate vaccine (serogroups A, C, W, Y, and X) for routine infant and toddler immunization in the African meningitis belt. At that time, only short-term data were available regarding persistence of elevated bactericidal antibody levels. This report provides data for the 2 years post-immunization.
