<p>DP1 associations with colorectal cancer by anatomic subsite. Top, HRs of quintile 5 versus quintile 1. Bottom, HRs of DP1 <i>z</i>-scores in continuous form. Unspecified (<i>n</i> = 68) and overlapping (<i>n</i> = 4) colorectal cancers were excluded as they could not be localized to an anatomic subsite. Test for trend down using LRTs. LRT, likelihood ratio test.</p>
