Gestational Glucose Intolerance and the Risk of Hypertensive Disorders of Pregnancy.
Article in Journal of the American Heart Association, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundWe evaluated associations between untreated mild hyperglycemia and hypertensive disorders of pregnancy.
methodsIn this retrospective study at a US academic medical center practicing universal 2-step gestational diabetes (GD) testing, we defined normal glucose tolerance as a normal screening 50-g, 1-hour glucose load test (<140 mg/dL). If the glucose loading test was abnormal, a diagnostic 100-g, 3-hour oral glucose tolerance test was performed. We defined GD as ≥2 abnormal oral glucose tolerance test values (Carpenter-Coustan criteria) and gestational glucose intolerance (GGI, untreated subclinical hyperglycemia) as 0 (GGI-0) or 1 (GGI-1) abnormal oral glucose tolerance test value. We divided GD into treated and untreated (given use of older diagnostic criteria in the study period). We examined associations between GGI or GD and hypertensive disorders of pregnancy (primary outcome) or its subtypes (gestational hypertension, preeclampsia) using generalized estimating equations with confounder adjustment.
resultsAmong 41 484 pregnancies, 84% had normal glucose tolerance, 12% had GGI (GGI-0: 9.0%, GGI-1: 3.0%) and 3.5% had GD. There was greater risk of hypertensive disorders of pregnancy in GGI compared with normal glucose tolerance (adjusted odds ratio [aOR], 1.24 [95% CI, 1.11-1.38]). This was attributable to increased risk in GGI-1 (aOR, 1.53 [95% CI, 1.27-1.85]), similar to untreated GD (aOR, 1.76 [95% CI, 1.37-2.26]). The risk of gestational hypertension was increased in GGI-1 (aOR, 1.66 [95% CI, 1.30-2.12]) and untreated GD (aOR, 1.89 [95% CI, 1.36-2.63]) but not in treated GD (aOR, 0.84 [95% CI, 0.58-1.23). The risk of preeclampsia was similarly increased in GGI-1, treated GD, and untreated GD (aOR, 1.46-1.75).
conclusionsMild untreated hyperglycemia in pregnancy is associated with hypertensive disorders of pregnancy; hyperglycemia treatment is associated with reduced gestational hypertension risk.
