  1. This table shows an overview of the model outcomes in terms of mean effectiveness and costs on an individual patient level. The mean model outcomes (and accompanying 95% CIs) are shown for the procalcitonin (PCT) group and the standard of care group. In addition, the differences between these groups (and accompanying 95% CIs) are provided
