It is important to note that there have been numerous retrospective studies (i.e. historical observations) performed on the use of phosphatidylcholine injections for fat dissolution1,2and a few prospective non-placebo-controlled studies performed to test the efficacy of the procedure.11 However, to date there have been no prospective, placebo-controlled studies (those required for FDA approval) done on the use of PCDC for fat removal and therefore safety and efficacy cannot be confirmed. Placebo-controlled studies are those where participants are randomly assigned to receive either the placebo or the active substance. Neither the participant nor the doctor know which treatment the participant receives. The goal of this type of trial is to illustrate that it is the drug that is eliciting a response, not the placebo. With retrospective studies, one makes conclusions based on pre-existing data (i.e. you start with an answer and look backwards to selectively find data that supports your co
