Abstract Many studies have examined the association between paraoxonase 1 (PON1) -L55M polymorphisms and risk of coronary heart disease (CHD), but the results remained inconsistent. We therefore aimed to address this association by performing an updated meta-analysis in the Chinese population. The PubMed, EMBASE, Web of Science, and Chinese National Knowledge Infrastructure were searched up to May 2020. The strength of statistical association was assessed with odds ratio (OR) and 95% confidence interval (CI). A total of eight studies with 1826 CHD cases and 1817 controls were finally included in the analysis. In the overall and subgroup analyses by control sources and geographic areas, the results showed no significant associations with CHD among all analysis models. Furthermore, we performed the analysis by including or excluding the HWE-violating studies. The results suggested that the MM genetype were significantly associated with CHD in studies not consistent with HWE under recessive and dominant models. This meta-analysis demonstrates that the PON1 -L55M polymorphism may not be associated with CHD risk in the Chinese population. Further studies with strict selection of patients and controls in different ethnic populations will be required to clarify this finding.
