3. Fig. 2
Conventional meta-analysis forest plots for 50% responder rate. Plots indicate the observed I2 values and associated P-value for heterogeneity from the conventional meta-analysis, along with the effect estimates and 95% CIs. Asterisks indicate an insufficient number of studies in the comparison to undertake heterogeneity testing. Diamond shape indicates overall treatment effect with 95% CIs. CI, confidence interval; OR, odds ratio; M–H, Mantel–Haenszel (fixed effects); D+L, DerSimonian and Laird (random effects).

4. Fig. 3
Conventional meta-analysis forest plots for seizure freedom. Plots indicate the observed I2 values and associated P-value for heterogeneity from the conventional meta-analysis, along with the effect estimates and 95% CIs. Asterisks indicate an insufficient number of studies in the comparison to undertake heterogeneity testing. Diamond shape indicates overall treatment effect with 95% CIs. CI, confidence interval; OR, odds ratio; M–H, Mantel–Haenszel (fixed effects); D+L, DerSimonian and Laird (random effects).

Conventional meta-analysis forest plots for study withdrawals. Plots indicate the observed I2 values and associated P-value for heterogeneity from the conventional meta-analysis, along with the effect estimates and 95% CIs. Asterisks indicate an insufficient number of studies in the comparison to undertake heterogeneity testing. Diamond shape indicates overall treatment effect with 95% CIs.

6. Fig. 5
Conventional meta-analysis forest plots for selected adverse events. Plots indicate the observed I2 values and associated P-value for heterogeneity from the conventional meta-analysis, along with the effect estimates and 95% CIs. Asterisks indicate an insufficient number of studies in the comparison to undertake heterogeneity testing. Diamond shape indicates overall treatment effect with 95% CIs. CI, confidence interval; OR, odds ratio; M–H, Mantel–Haenszel (fixed effects); D+L, DerSimonian and Laird (random effects).
