Their discontinuation ratio was 31.4% compared with 39.0% for older tricyclic antidepressants (P< 0.001). They also had lower discontinuation ratios for side effects compared with older tricyclics (12.9% v 18.0%; P< 0.0001)."

The average number of events reported was 4.1 with dothiepin treated patients and 3.6 for those treated by placebo. There was no statistically significant difference between treatments in the proportion of patients reporting adverse events."

> There are disadvantages of comparing groups of compounds against each other. Tricyclics are heterogeneous. Smaller meta-analyses have been done to compare individual drugs. Dothiepin has been compared against the SSRIs (Donovan et al, 1993). [10] The meta-analysis was based on three trials comparing fluoxetine with dothiepin and found that the drop-out rate for adverse events was lower for dothiepin. Unfortunately the authors did not perform a stratified analysis. We re-analysed their results using a Mantel-Haenzel method (i.e. fixed effects estimate; Mantel-Haenzel analysis allows a stratification of result by study, thus weighting the analysis in favour of larger studies) and the odds ratio for drop outs in fluoxetine versus dothiepin was 1.79 (95% CI 0.89-3.79, P=0.08; i.e. more drop-outs in fluoxetine, but not statistically significant).Thanks for this explanation!
