Prevalence of symptomatic and subclinical phenotypes in the 770 CD patients. Note that 610 patients (79%) were diagnosed as symptomatic, whereas the remaining 160 (21%) were classified as subclinical CD. Of the 610 symptomatic patients, 210 (34%) displayed the classical onset with diarrhea and malabsorption (regardless of extraintestinal manifestations), whereas the other 400 showed the non-classical form with gastrointestinal symptoms (other than diarrhea) and extraintestinal manifestations.
