Background: Declining birth rates during the pandemic have led to concerns about the potential impact of the of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on fertility among men. As previous studies have had inconsistent conclusions, we conducted a meta-analysis to evaluate the effects of SARS-CoV-2 on semen parameters.
Methods: We searched several databases for articles published between 1 January 2020 and 25 July 2023.
Purpose: This study aimed to investigate the association between the CC-cytokine ligand-2 (CCL2) 2518A/G (rs1024611) single nucleotide polymorphism (SNP) and susceptibility to age-related macular degeneration (AMD).
Methods: PubMed, Embase, Web of Science, and other databases were searched for articles published before August 24, 2023. After searching, data extraction, and quality assessment, meta-analysis and trial sequential analysis were conducted using RevMan 5.
Aim: Our study aimed to assess the association between gene 3' untranslated region insertion/deletion (3'UTR I/D) and A55V (alanine/valine) polymorphisms and neural tube defects (NTDs) susceptibility.
Materials And Methods: According to pre-determined inclusion and exclusion criteria, the article search was conducted to search articles published before October 2023. Two authors independently screened the included articles and extracted their basic characteristics.
Background: The current understanding of the correlation between TLR4 gene (toll-like receptor 4) rs4986790 and rs4986791 polymorphisms and asthma susceptibility is inconclusive, with studies and populations yielding conflicting results.
Objectives: Evaluate this relationship using meta-analysis and trial sequential analysis (TSA).
Patients And Methods: Databases were systematically queried for relevant articles from the establishment of the database to 19 June 2023 adhering to predefined inclusion and exclusion criteria.
Background: Although numerous case-control studies have explored the association between CC cytokine ligand-4 (CCL4) expression and cancer susceptibility, their results have been conflicting. This study aimed to determine the still-unknown connection of CCL4 rs10491121 and rs163450 polymorphisms with cancer susceptibility.
Methods: Several databases, such as Web of Science, PubMed, and EMBASE, were searched for papers published since the creation of the database until November 2, 2022.
Our study is aimed to access the efficacy and safety outcomes for coronavirus disease 2019 (COVID-19) patients treated with Paxlovid. According to inclusion and exclusion criteria, databases were used to retrieve articles from 1 January 2020 to 1 January 2023. Article screening, quality evaluation and data extraction were completed and cross-checked.

This meta-analysis aimed to offer a systemic review of HFMD susceptibility and severity among the Chinese Han population associated with the C/T (rs3775290) polymorphism of the TLR3 gene or C/G (rs3853839) polymorphism of the TLR7 gene.
Methods: A computer search was conducted using PubMed, Web of Science, Embase, CNKI, CBM, VIP, and WanFang databases.
