Figure 3: (a) The data indicates an increasing incidence of CMM in the white population of the USA for six decades at three latitudes: ~34°N (average of Los Angeles, California; Atlanta, Georgia; New Mexico), 39°N (average of San Francisco, California, and Utah) and 43°N (average of Iowa, Michigan, Connecticut, and Upstate New York). The CMM incidences at 34°N and 43°N are increasing at exponential rates while at 39°N, it is increasing at a linear rate (determined by comparing values for the linear and exponential trend lines). (b) The CMM incidence data at 39°N changes from linear to exponential and the 43°N data changes from exponential to linear when Connecticut is averaged with San Francisco and Utah.
