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

Background: This review aims to conduct a comprehensive and systematic report of the currently published information on the association between elevated hepcidin levels and the risk of preeclampsia by meta-analysis of published prospective case-control studies or cross-sectional studies combined with follow-up to provide a comprehensive and reliable basis for early intervention and clinical decision making in the disease. Methods: We searched five databases such as Pubmed, Web of Science, Cochrane, China National Knowledge Infrastructure, and WAN FANG DATA to retrieve articles related to the relationship between elevated levels of hepcidin and the risk of preeclampsia up to February 2025. We calculated the standardized mean deviation (SMD) and 95% confidence interval (95% CI) for comparison using a random-effects model.
