Although a placebo group is listed, no data are posted for the "placebo" group where patients did not receive either Varivax or Proquad. The editor or reader cannot therefor evaluate whether the placebo group showed any change in their titers of varicella. So this study should not be listed as placebo controlled without complete data.
