Relationships between colorectal cancer characteristics and CRC screening resources in Mississippi’s Public Health Districts. Data listed in Table 1 were subjected to a common Spearman rank correlation analysis. Two associative trends were observed. There is a positive association (R = 0.649, P = 0.058) between self-reported CRC screening rates and the ratio of gastroenterologists per facilities offering colonoscopies (panel a), and there is a comparable positive association (R = 0.649; P = 0.058) between colorectal cancer mortality rates and the number of residents per gastroenterologists (panel b)
