Combined AGT M235T-ACE I/D genotype and risk of essential hypertension in Vietnamese adults: a hospital-based case-control study.

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
backgroundEssential hypertension is influenced by conventional risk factors and genetic susceptibility. We tested the prespecified hypothesis that the combined AGT M235T-ACE I/D TT/DD genotype is associated with essential hypertension in Vietnamese adults.
methodsWe conducted a hospital-based case-control study among 471 Vietnamese Kinh adults at the University Medical Center, Ho Chi Minh City, Vietnam, including 238 cardiology-clinic participants with essential hypertension and 233 health-screening participants without hypertension. Hypertension was defined according to Vietnamese guideline thresholds as office systolic blood pressure ≥140 mmHg and/or diastolic blood pressure ≥90 mmHg, or current antihypertensive treatment; controls had no history of hypertension, were not receiving antihypertensive medication, and had office blood pressure < 140/90 mmHg. The primary exposure was TT/DD versus non-TT/DD. Multivariable logistic regression adjusted for age, sex, overweight or obesity, diabetes mellitus, salt-rich diet, smoking, alcohol misuse, physical inactivity, and family history of hypertension.
resultsTT/DD was observed in 37 of 238 cases (15.55%) and 15 of 233 controls (6.44%). TT/DD was associated with hypertension in crude analysis (OR 2.67, 95% CI 1.38-5.40; p = 0.002) and remained associated after adjustment (adjusted OR 3.26, 95% CI 1.53-6.92; p = 0.002). In an exploratory six-category model using (MM + MT)/II as the reference, TT/DD was the only genotype category significantly associated with hypertension, although the estimate was imprecise (adjusted OR 3.46, 95% CI 1.24-9.70; p = 0.018).
conclusionsThe combined AGT M235T-ACE I/D TT/DD genotype was associated with essential hypertension in this hospital-based Vietnamese sample. Because of the case-control design, hospital-based recruitment, covariate imbalance, and absence of external replication, the finding should be interpreted as associative and hypothesis-generating.
