Pedro Martínez: US's ranking on infant mortality as a direct cooresponding factor to the quality of US health care was the connection that was being made. I have shown that making such an analysis based on that single factor is faulty at best. It should concern all Americans that the infant mortality rate is high. But to conclude that it's the fault of the health care system ignores more likely factors. If all data collecting were equal, then the comparisons would have more meaning.
