This chart is a compilation of studies organized by Sam Ziff of Bio-Probe, Inc. A total of 1569 patients participated. We’ve arranged the results to emphasize the Percentage Improved or Cured, highlighting those symptoms most improved solely from the removal of mercury fillings. The other columns also yield important data. For example, the Percentage with Symptom and the Total Number of Symptoms columns show that the most common symptoms related to mercury-amalgam fillings in this particular study are fatigue, headaches, vision problems, and depression. But as you can see, it covers a vast array of mercury related symptoms. 

Before and after the removal of their mercury fillings (amalgam fillings), patients were evaluated for the symptoms listed in the chart. Allowing for minimal variables, the only constant was that all participants had their amalgam / mercury fillings removed. It is common sense that if a symptom wasn’t related to mercury poisoning, it wouldn’t show improvement after the fillings were removed.
