Figure 6From: A comparative analysis of aspatial statistics for detecting racial disparities in cancer mortality ratesMaps of counties with significantly greater prostate cancer mortality rates for black males. The threshold difference Δ0 is expressed either in absolute term (deaths/100,000 habitants) or percentage, depending on the type of statistic used (RD versus RR type). One-tailed tests were conducted at a significance level α = 0.01. White polygons depict non-significant (NS) differences, while hatched areas correspond to missing data. Thicker lines delineate state boundaries. The pointing arrows in the right maps indicate the two counties (Alamance, NC: FIPS 37001, Jefferson, AL: FIPS 1073) with the smallest p-value for the one-tailed tests.Back to article page
