Cross-sectional associations between plasma copper, zinc and prediabetes among rural Indian adolescent girls: baseline data from the DERVAN cohort (DERVAN-8).
Article in Journal of biosciences, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Copper and zinc are essential minerals for proper metabolic function, and their imbalance could potentially cause prediabetic conditions. We investigated associations of copper and zinc with glycaemic parameters in 1473 adolescent girls aged 15-18 years at baseline in the DERVAN cohort study. Anthropometric indices, glucose, insulin and glycated haemoglobin were measured, and prediabetes was diagnosed using American Diabetes Association criteria. Copper was positively associated with fasting glucose, insulin and insulin resistance, and inversely associated with insulin sensitivity. Zinc was positively associated with fasting glucose and inversely associated with beta-cell function. In multivariate analysis, girls in the third and fourth quartiles of plasma copper had significantly higher odds of prediabetes than those in the lowest quartile. Longitudinal follow-up of the cohort will clarify whether these trace minerals contribute to progression toward diabetes.
