Title:Hospital-based, prospective, multicentre surveillance to determine the
incidence of intussusception in children aged < 15 years in Germany
Version: 1Date:28 December 2010
Reviewer: Yi-Hau Chen
Reviewer's report:
This manuscript presents a detailed statistical procedure for estimating the IS
incidence rate, adjusting for under-reporting. The estimation procedure seems
correct and suitable. Some minor comments follow.
(1) It would be helpful to show a figure for the estimated distribution of
underreporting of IS cases V(p).
(2) I cannot understand the statement on the middle of page 12: "For the age
group below two years of age and below one year of age this is the case for 10
and 11 hospitals, respectively." Please clarify.
Level of interest: An article whose findings are important to those with closely
related research interests
Quality of written English: Acceptable
Statistical review: Yes, and I have assessed the statistics in my report.
