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
What is already known about this topic?: Elevated ferritin levels have been associated with increased insulin resistance, impaired insulin secretion, and heightened risk of type 2 diabetes in non-pregnant populations. However, the relationship between ferritin concentrations and the development of gestational diabetes mellitus (GDM) remains poorly understood. What is added by this report?: This study identified a U-shaped association between serum ferritin measured at 11-13 weeks of gestation and GDM risk, demonstrating that both low and high ferritin levels predict increased GDM incidence. Additionally, elevated ferritin concentrations at 16-19 weeks and 24-27 weeks of gestation were independently associated with greater GDM risk. What are the implications for public health practice?: These findings underscore the critical importance of monitoring serum ferritin throughout the first and second trimesters for early identification and prevention of GDM. Enhanced strategies are needed to improve clinical understanding and optimize the utility of ferritin assessment in prenatal care.
