Title.Rhubarb eating does not protect against colorectal cancer

Abstract

Background/rationale: Numerous environmental factors influence the incidence of colorectal cancer. Whether rhubarb eating is one of these factors is not known.

Objective: to determine the incidence of colorectal cancer in persons who regularly eat rhubarb compared with the incidence in persons who never eat rhubarb.

Methods: One thousand persons who eat rhubarb at least three times per week and 1000 persons who never eat rhubarb were evaluated with colonoscopy.

Results: The incidence of colorectal cancer in the rhubarb eaters was XXX%. The incidence in the non-rhubarb eaters was YYY%. The difference is not statistically significant (p >1.0).

*Conclusions: The incidence of colorectal cancer detected by colonoscopy in persons who regularly eat rhubarb and those who do not eat rhubarb was not statistically different. In this study population, rhubarb eating did not protect against colorectal cancer.

Introduction

*Concluding sentence: In order to help determine if rhubarb protects against colorectal cancer, we examined, by colonoscopy, persons who regularly eat rhubarb and those who do not eat rhubarb.

Discussion

*Opening sentence: In this study, designed to help determine whether rhubarb eating protects against colorectal cancer, we found a similar incidence of cancer, detected by colonoscopy, in persons who regularly eat rhubarb and those who do not eat rhubarb.

*Conclusion(s): The incidence of colorectal cancer, detected with colonoscopy, was similar in persons who regularly eat rhubarb and those who do not eat rhubarb. Thus, rhubarb eating did not protect against colorectal cancer in this study population.
