The many failures to correct associated metabolic disturbances, revealed by biochemical observations, is a clear indication that the disease is not caused primarily by hemic changes, but is rather a result of hitherto unrecognized factors. Its frequent occurrence in Central and South China also eliminates the so often mentioned dietetic, racial and climatic preferences of the disease.
