Li et al reported a model for predicting colorectal adenomatous polyps in an adult. This can help to identify a patient to monitor more closely. The authors are from Nanjing Medical University.
Patient selection: adult with age >= 18 years
Parameters:
(1) age in years
(2) gender
(3) hyperlipidemia
(4) high consumption of red meat
(5) high consumption of salt
(6) high consumption of dietary fiber
(7) Helicobacter pylori
(8) NAFLD
(9) chronic diarrhea

total score =
= SUM(points for all of the parameters)
Interpretation:
• minimum score: 0
• maximum score: 264.4
value of X =
= (0.02641 * (score)) - 1.797
probability of colorectal adenomatous polyps =
= 1 / (1 + EXP((-1) * X))
Performance:
• The area under the ROC curve is 0.78.
