This study set out to estimate whether the TLR9 rs352140 polymorphism confers an increased risk of BM. Relevant literature databases were searched including PubMed, Embase, the Cochrane Library and China National Knowledge Infrastructure (CNKI) up to August 2020. Seven case-control studies from four publications were enrolled in the present meta-analysis. Odds ratios (OR) and confidence intervals (95% CI) were calculated to estimate associations between BM risk and the target polymorphism. Significant associations identified were allele contrast (A <jats:italic>vs.<\/jats:italic> G: OR 0.66, 95% CI 0.59\u20130.75, <jats:italic>P<\/jats:italic> = 0.000), homozygote comparison (AA <jats:italic>vs.<\/jats:italic> AG\/GG: OR 0.62, 95% CI 0.49\u20130.78, <jats:italic>P<\/jats:italic> = 0.000), heterozygote comparison (A <jats:italic>vs.<\/jats:italic> G: OR 0.74, 95% CI 0.61\u20130.91, <jats:italic>P<\/jats:italic> = 0.005), recessive genetic model (AA <jats:italic>vs.<\/jats:italic> AG\/GG: OR 0.78, 95% CI 0.65\u20130.93, <jats:italic>P<\/jats:italic> = 0.006) and dominant genetic model (AA <jats:italic>vs.<\/jats:italic> AG\/GG: OR 0.70, 95% CI 0.57\u20130.85, <jats:italic>P<\/jats:italic> = 0.000). The findings indicate that, in contrast to some studies, the TLR9 rs352140 polymorphism is associated with a decreased risk for
