RESULTS: Totally 7 studies including 3247 cataract patients were eligible among 208 papers screened in our search. The odds ratio(OR)was 1.20(95%CI, 1.01-1.38). Subgroup analysis indicated latitude was covariate that led to heterogeneous. Sensitivity analysis confirmed our results' stability.

CONCLUSION: The meta-analysis results prompted hypertension can increase the risk of cataract of the Chinese population.
