Mean gametocyte density/μl during follow up in ACT (black, circles) and non-artemisinin (grey, triangles) antimalarial treatment groups, pooled results from the six trials (a) overall (b) stratified by parasitological treatment failure (c) stratified by presence of pre-treatment gametocytes. Error bars show 95% confidence intervals. Lines drawn in between data points are theoretical only. Below: ratios showing ACT impact on gametocyte prevalence and density on each follow up day, allowing for random study effects.
