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
Iron overload increases fasting blood glucose level in mice, leading to insulin insensitivity. However, no such relationship has been shown in the population. The relationship between whole blood iron levels and fasting blood glucose levels remained unclear. This study aimed to determine whether whole blood iron levels were associated with fasting blood glucose levels in community-dwelling older adults. This cross-sectional study was based on a community population and analyzed the distribution of whole blood iron and fasting blood glucose in a community population. A sample of 1560 community residents had their fasting blood glucose, gender, and age measured during the study. Covariates were assessed using correlation analysis, partial correlation analysis, and Student's t-test. To further investigate the impact of confounding factors in this study, we compared variations in whole blood iron levels between genders. Pearson correlation analysis showed no correlation between whole blood iron and fasting blood glucose. After adjusting for age and gender, no correlation was found between whole blood iron and fasting blood glucose as well. However, Pearson correlation analysis showed a correlation between whole blood iron and age(P<0.05, r=-0.181). whole blood iron concentrations gradually decreased with age. At the same time, mean whole blood iron concentrations were lower 420 mg/l among women and men in the community. And the mean levels of whole blood iron were higher in men(504.08 mg/l ± 45.98 mg/l) than in women(453.80 mg/l ± 38.13 mg/l). Our study indicated no association between whole blood iron. Age was a covariate, but fasting blood glucose was not, and fasting blood glucose was independently associated with whole blood iron concentrations, suggesting that older women in this community need adequate iron supplementation.
