Adjusted1 OR and 95% CI for metachronous high risk adenoma and serrated polyp ≥ 1cm by index colonoscopy findings of high risk adenoma and serrated polyp (size and histology) among 4,015 NHCR participants with 2 colonoscopies (1/2004–6/2015)
Abbreviations: OR = odds ratio, CI = confidence interval, NHCR = New Hampshire Colonoscopy Registry, HRA=high risk adenoma, SP = serrated polyp, STSA = sessile or traditional serrated adenoma, HP = hyperplastic polyp
1Adjusted for patient age, gender, smoking status, BMI and median time between the 2 colonoscopies Reference line (1.00) = no adenoma and no serrated polyp; Blue diamond = OR and printed above diamond Note: All four panels scaled to 0–40; Index Findings (size) HRA, SP>1cm CI extends to 80 for SP ≥ 1 cm
