Of the 199 respondents, 7 responded that they did not perform colonoscopy and were therefore excluded from characterization of socio-demographics. Among the 192 eligible subjects, 1 physician did not provide a response to the question on number of colonoscopies per month, and 3 physicians did not respond to the question on familiarity with guidelines.

Percentages are calculated using denominator of 192, and rounded to nearest whole number
