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

Introduction: We examined the effects of a whole-grain intervention on serum vitamin D levels in pre-diabetic individuals in China. Methods: Participants aged 18-65 years at risk of diabetes participated in a 12-week randomised parallel controlled trial. Intervention groups consumed 50 g/day and 100 g/day of whole grains, whereas the control group maintained a regular diet. All participants received nutritional guidance. Serum 25-hydroxyvitamin D levels were monitored at baseline, 6 weeks, and 12 weeks using liquid chromatography-tandem mass spectrometry. Results: At 6 weeks, serum 25-hydroxyvitamin D levels remained insufficient across all groups. By 12 weeks, both intervention groups showed significant increases, reaching adequate levels, whereas the control group remained at the lower limit of adequacy. Conclusion: Sustained whole-grain intake improves vitamin D status in pre-diabetic individuals.
