Table 3.

Sensitivity analyses: Percent of disparities in CRC incidence and mortality between blacks and whites aged 50 years and older explained by screening and survival.

Sensitivity analysis	CRC incidence disparity % explained by screening	CRC mortality disparity
		% explained by screening	% explained by survival	% explained by screening and survival*
Base case analysis	42%	19%	36%	54%
Lower-quality endoscopy in blacks	68%	34%	36%	66%
25% remaining survival difference	42%	19%	28%	46%
Same stage distribution as whites	42%	19%	57%	60%

^*Because of synergy in effects separate effects of screening and survival do not add up.
