Geographic Variation of Chronic Kidney Disease Prevalence: Correlation with the Incidence of Renal Cell Carcinoma or Urothelial Carcinoma?

Figure 1

Risk categorization after combining age-adjusted standardized morbidity rates (ASMR, expressed as percentage) groups of both year 2010 and year 2009.  Indeterminate = chronic kidney disease prevalence of townships being zero (unable to perform goodness-of-fit test). Significant ASMR in either year: Low, either = Significant ASMR < 1.76% in either year; High, either = Significant 1.76% ≤ ASMR < 2.64% in either year; Higher, either = Significant ASMR ≥ 2.64% in either year. Nonsignificant of ASMR in both years: Nonsignificant, both = ASMR is not significant comparing with whole study populations in both years. Significant ASMR in both years: Low, both = ASMR < 1.76% for both years; High, both = ASMR < 1.76% in either year and 1.76% ≤ ASMR < 2.64% in another year/1.76% ≤ ASMR < 2.64% for both years; Higher, both = 1.76% ≤ ASMR < 2.64% in either year and ASMR ≥ 2.64% in another year; Highest, both = ASMR ≥ 2.64% for both years.
