Selenium intake modifies the association of dietary fat with hypertension among Chinese adults: a cohort 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
Background: The role of selenium intake on the association of fat intake with hypertension remains unclear. This study aimed to investigate the relationship among selenium intake, dietary fat and hypertension risk among Chinese adults. Methods: Data from the China Health and Nutrition Survey were used. Individuals who were free of hypertension at baseline (2004) and participated at least once in the subsequent surveys (2006, 2009, and 2011) were included in this study. Generalized estimating equation models were used to explore the relationship between fat intake and systolic and diastolic blood pressure, and hypertension risk, as well as the modifying effect of selenium intake. Results: Among a total 5,643 participants, 1,722 adults developed hypertension during the follow-up period. After adjusting for covariates, participants in the highest fat intake group had significantly increased risk of hypertension compared with the lowest group (OR: 1.22, 95% CI: 1.01-1.47). The risk of hypertension tended to increase with increasing fat intake in the low selenium intake group, but not in the high selenium intake group. Systolic blood pressure increased by 0.69 mmHg (95% CI: 0.17-1.22) with increasing 50 g/day fat intake in the low selenium intake group (T1), whereas this association was not significant in the selenium intake T2 and T3 groups. Conclusion: Selenium intake may modify the relationship between fat intake and hypertension, with high selenium intake attenuating the negative effects of fat intake on hypertension risk.
