Hypothesis
This study aims to meta-analyze three eNOS polymorphisms in association with hypertension across different ethnic populations.
Conclusion
The study confirms the role of eNOS G894T and 4b/a polymorphisms in hypertension for Asian populations and Tâ786C polymorphism for Whites.
Supporting Evidence
- The G894T polymorphism showed a 16% increased risk for hypertension across all populations.
- In Asians, the G894T polymorphism was associated with a 32% increased risk for hypertension.
- The 4b/a polymorphism was linked to a 29% increased risk for hypertension in all populations.
Takeaway
This study looked at how certain genes might affect blood pressure in different groups of people, finding that some gene variations can increase the risk of high blood pressure.
Methodology
Data were analyzed using Stata software with a random-effects model, and publication bias was assessed using Egger's test.
Potential Biases
There was a high probability of publication bias, particularly for the G894T polymorphism.
Limitations
The study is limited by the cross-sectional design of included studies and the lack of data on important intermediate phenotypes.
Participant Demographics
The study included various ethnic populations, specifically focusing on Asian and White groups.
