Figure 2. Forest plot of the association between rs6165 polymorphism and PCOS in allelic model (first forest plot, Ala vs. Thr), recessive model (second forest plot, Ala/Ala vs. Ala/ Thr+Thr/Thr) and dominant model (third forest plot, Ala/Ala+Ala/Thr vs. Thr/Thr). Solid squares are OR from individual studies, horizontal lines are 95% CI. Pooled OR with 95% CI are presented in diamonds.
