Fig. 2From: The association between genetic variants in lactotransferrin and dental caries: a meta- and gene-based analysisFunnel plot for meta-analysis of the association of rs1126478 with dental caries assuming an additive model. The x-axis is the odds ratio, and the y-axis is the standard error of estimated effect of rs1126478 on risk of dental caries. The vertical line in the figure represents the overall estimated odds ratio. The two diagonal lines represent the pseudo 95% confidence limits of the effect estimateBack to article page
