Organic Pollutants and Risk of Type 2 Diabetes: A Systematic Review and Meta-analysis.
Article in Mayo Clinic proceedings. Innovations, quality & outcomes, 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
Objective: To evaluate the associations between organic pollutants (OPs) and risk of type 2 diabetes (T2D). Patients and Methods: We searched Medline, Embase, Scopus, Web of Science, and Cochrane Central from inception through March 18, 2024. We included studies reporting the adjusted or unadjusted association between serum concentration of OPs and risk of T2D. We excluded studies on type 1 diabetes, self-reported exposure, and if fewer than 100 T2D cases. We classified OPs using 2 classification methods and reported pooled risk estimates using a random-effects model (odds ratio [95% CI]) and assessed risk of bias at the levels of OPs and their classes. We conducted sex- and concentration-stratified analyses. Results: From 20,531 articles, we included 44 (0.2%) studies of 83 individual and 38 combination OPs in 54,967 participants. All but 1 study had low risk of bias. Ten of 12 OP classes were associated with risk of T2D, polychlorinated dibenzo-p-furans had the highest association (OR, 2.54; 95% CI, 1.94-3.33). Polychlorinated dibenzo-p-dioxins showed a significant association in men (OR, 3.21; 95% CI, 1.81-5.71). Polychlorinated biphenyls (OR, 1.72; 95% CI, 1.55-1.92) and dichlorodiphenyltrichloroethane (DDT) and DDT-like compounds (OR, 1.14; 95% CI, 1.01-1.29) showed a significant association in women. Moreover, 28 (33.7%) individual and 21 (55.3%) combination OPs had a significant association. Polychlorinated biphenyl 157 (OR, 1.93; 95% CI, 1.27-2.92) and organochlorine pesticides (OR, 4.35; 95% CI, 1.90-9.98) had the highest risk of T2D. Conclusion: Several OPs were associated with higher risk of T2D. Future work should evaluate the concentration threshold at which OPs increase risk to inform both T2D screening and OP advisories and regulation.
