Total vegetables & Fruits and lung cancer.

Sometimes data about vegetables & fruits is not stratified into total vegetables vs total fruits. This page contains information from articles in which data was not stratified into vegetables vs fruits.
Stratified data about 2 of the 3 cohorts on this page (11, 19) was provided by other articles on these cohorts, though. Therefore, only data about "The NHANES I Epidemiologic Followup Study" presents additive information (12). This cohort was of very small size and no quartiles of consumption were defined.
