Association between diabetes phenotypes with hypertension and cardiovascular diseases, using single-sample confirmatory testing: a national study.
Article in Acta diabetologica, 2025. 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
aimTo investigate, for the first time, the association between undiagnosed diabetes-using a single-sample confirmatory definition-and prevalent hypertension and cardiovascular diseases (CVD) in an Iranian national population. A few studies on this topic have been limited to Western populations.
methodsThe study included 16328 adults aged ≥ 30 years. Diabetes phenotypes were classified as: 1-no diabetes: fasting plasma glucose (FPG) < 7 mmol/L (126 mg/dL) and glycated hemoglobin (HbA1c) < 6.5% (48 mmol/mol), as reference; 2-unconfirmed undiagnosed diabetes: having elevated levels of either FPG or HbA1c; 3-confirmed undiagnosed diabetes: having elevated levels of both tests; 4-known diabetes: self-reported history of glucose-lowering medications. Hypertension was defined using American Heart Association criteria. Self-reported history of CVD is defined as prevalent CVD. Multivariable logistic regression models were applied to estimate the odds ratio (OR) and 95% confidence interval (CI) of the association between diabetes phenotypes with hypertension and CVD.
resultsPrevalence of unconfirmed undiagnosed-, confirmed undiagnosed-, and known -diabetes was calculated as 2.70, 3.10, and 5.64%, respectively. Unconfirmed undiagnosed-, confirmed undiagnosed-, and known -diabetes were associated with hypertension with corresponding OR were, 1.30, 1.37, and 1.62; the related values for CVD were 1.80, 1.61, and 2.38; and for the coexistence of CVD and hypertension were 1.86, 1.79, and 2.80, respectively (all P
conclusionsBoth unconfirmed- and confirmed- undiagnosed -diabetes were significantly associated with hypertension and CVD, the issue that was mainly attributable to high HbA1c.
