Figure 7
Forest plots for the association between combined Exon1 polymorphisms (involving A/O allele = C,G,G/T,A,A alleles of rs5030737, rs1800450 and rs1800451 polymorphisms respectively) and RVVI under the (a) allelic, (b) homozygote, (c) heterozygote, (d) dominant and (e) recessive mode of inheritance for the studies including De Seta et al.16 and Milanese et al.10. Black boxes represents the value of odds ratio (OR) and the size of the boxes is inversely proportional to the size of the result study variance, so that more precise studieshave larger boxes. Horizontal line is the 95% Confidence Interval (CI) of OR. The summary OR is represented by the diamond, where the center of the diamond indicates the OR. The ES is effect size expressed as OR; W, weight; Sig, statistical significance; N1, cases; N2, controls.
