Author contributions: Lai M and Qin YL conceived, designed, and refined the study protocol; Lai M, Qin YL, Jin QY, Chen WJ, and Hu J were involved in the data collection; Lai M, Qin YL, and Jin QY analyzed the data; Lai M and Qin YL drafted the manuscript; all authors were involved in the critical review of the results and have contributed to, read, and approved the final manuscript. Lai M and Qin YL contributed equally to this work as co-first authors. The reasons for designating Lai M and Qin YL as co-first authors are threefold. First, the research was performed as a collaborative effort, and the designation of co-first authorship accurately reflects the distribution of responsibilities and burdens associated with the time and effort required to complete the study and the resultant paper. This also ensures effective communication and management of post-submission matters, ultimately enhancing the paper's quality and reliability. Second, the overall research team encompassed authors with a variety of expertise and skills from different fields, and the designation of co-first authors best reflects this diversity. This also promotes the most comprehensive and in-depth examination of the research topic, ultimately enriching readers' understanding by offering various expert perspectives. Third, Lai M and Qin YL contributed efforts of equal substance throughout the research process. The choice of these researchers as co-first authors acknowledges and respects this equal contribution, while recognizing the spirit of teamwork and collaboration of this study. In summary, we believe that designating Lai M and Qin YL as co-first authors is fitting for our manuscript as it accurately reflects our team's collaborative spirit, equal contributions, and diversity.

Abstract
BACKGROUND

The MBOAT7 rs641738 single-nucleotide polymorphism (SNP) has been proven to influence various liver diseases, but its association with hepatocellular carcinoma (HCC) susceptibility has been debated. To address this discrepancy, we conducted the current systematic review and meta-analysis.

AIM

To perform a systematic review and meta-analysis on association of MBOAT7 SNP and HCC susceptibility.

METHODS

We performed a systematic review in PubMed, Web of Science, Scopus, and EMBASE; applied specific inclusion and exclusion criteria; and extracted the data. Meta-analysis was conducted with the meta package in R. Sensitivity and subgroup analyses were also performed. This meta-analysis was registered in PROSPERO (CRD42023458046).

RESULTS

Eight studies were included in the systematic review, and 12 cohorts from 6 studies were included in the meta-analysis. Our meta-analysis revealed an association between the MBOAT7 SNP and HCC susceptibility in both the dominant [odds ratio (OR): 1.14, 95% confidence interval (95%CI): 1.02-1.26, P = 0.020] and recessive (OR: 1.21, 95%CI: 1.05-1.39, P = 0.008) models. Subgroup analysis revealed that stratification of the included patients by geographical origin showed a significant association in Asia (OR: 1.20, 95%CI: 1.03-1.39).

CONCLUSION

This meta-analysis underscores the contribution of the MBOAT7 rs641738 SNP to hepatocarcinogenesis, especially in Asian populations, which warrants further investigation.

Keywords: MBOAT7; Single-nucleotide polymorphisms; Hepatocellular carcinoma; Systematic review; Meta-analysis; Asian populations

Core Tip: We conducted the current systematic review and meta-analysis to address the association between MBOAT7 rs641738 SNP and HCC susceptibility. We demonstrated the correlation between MBOAT7 rs641738 SNP and HCC susceptibility both in the dominant and recessive models, and subgroup analysis revealed the significant association especially in Asia populations, which could guide clinical practice in the identification of at-risk population.
