Figure 4. Forest plot of the association between rs2479106 polymorphism and PCOS in a recessive model (GG vs. GA+AA). First forest plot: Total analysis of all included studies. Second forest plot: Subgroup analysis based on ethnicity, both Asians and Caucasians. Solid squares are OR from individual studies, horizontal lines are 95% CI. Pooled OR with 95% CI are presented in diamonds.

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.
