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

What is already known about this topic?: High population mobility frequently undermines public health efforts to maintain immunization coverage, as mobile families often face barriers to accessing consistent healthcare. What is added by this report?: Migration across provincial-level administrative divisions (PLADs) drives progressively widening coverage disparities while contributing to delayed vaccination and missed catch-up opportunities within the National Immunization Program (NIP) during the first three years of life in China. What are the implications for public health practice?: These findings underscore the need for a dynamic, life-course approach to migrant child immunization, with heightened focus on ensuring coverage during infancy. Vaccination verification and catch-up efforts should be intensified at preschool enrollment.
