Percent of patients due and overdue for CRC screening screened by each method by PCP cluster

	Cluster
Patient^* Screening Rate by Method (%)	Balanced	FOBT	FOBT & Flex Sig	Colonoscopy & FOBT	p-value
FOBT only	13.1^a	18.8^a,b,c	12.6^b	15.6^c	<.001

Means within a row with the same superscript (^a,b,c,d) are significantly different from one another based on LSD post hoc tests

Mean % per PCP of patients due or over-due for CRC screening as of January 1, 2009 who were screened by June 30, 2009

^†

Endoscopy- either FS, FS+FOBT, or colonoscopy

FOBT- fecal occult blood test, FS-flexible sigmoidoscopy, DCBE-double contrast barium enema
