Fig. 1: The scatter plots illustrate the significant causal relationship between the gut microbiota and dental caries.

The scatter plot of the effect size and 95% confidence interval of each SNP on gut microbiota and dental caries risk demonstrates the impact of each SNP on the risk of dental caries. The horizontal axis reflects the genetic effect of each SNP on gut microbiota, while the vertical axis represents the genetic effect of each SNP on dental caries risk. A Causal relationship between dental caries and Escherichia.Shigella. B Causal relationship between dental caries and Eubacteriumbrachygroup. C Causal relationship between dental caries and Oscillibacter. D Causal relationship between dental caries and Oscillospira. E Causal relationship between dental caries and RuminococcaceaeUCG014. F Causal relationship between dental caries and Terrisporobacter.
