5-HTTLPR PTSD SLC6A4 S allele vs L allele: OR=1.05; 95% CI=0.87, 1.26; P-value=0.63; I2=63; the dominant model,BDM (S+vs LL)OR=1.01;95% CI=0.78, 1.30; P-value=0.95; I2=57; the recessive model, BRM (SS vs L+) OR=1.15; 95%CI=0.82, 1.60; P-value=0.41; I2=55, respectively) (Figs 2, 3 and 4).Secondly, a meta-analysis of the triallelic approach offered similar results for the TFM model (OR=1.15; 95%CI=0.82,1.60; P-value=0.41; I2=74), for TDM model (OR=1.02; 95%CI=0.73, 1.48; P-value=0.93; I2= 43) and for the TRM (OR=1.31; 95%CI=71, 2.41; P-value=0.38; I2=80) (Figs 5, 6 and 7, respectively).0.66, 1.74; I2=78% and TFM, OR=1.14; 95% CI: 0.70, 1.87; I2=81%), in the dominant model (BDM, OR=1.09; 95% CI: 0.61, 1.96; I2=72%, TDM, OR=0.93; 95% CI: 0.60, 1.44; I2=39%) and in the recessive model (BRM, OR=1.05; 95% CI: 0.41, 2.67; I2=73%, TRM, OR=1.40; 95% CI: 0.54, 3.57;I2=85%). This is the first published meta-analysis of the relationshi...... This is the first published meta-analysis of the relationship between 5-HTTLPR polymorphisms and PTSD. They found no significant relationship between biallelic or triallelic polymorphism and PTSD, using the three possible approaches (allele frequency, dominant and recessive model). More...
