Numbers and rates with change during periods of interest (lockdown 1). "People" represent total number of people in Germany in the respective year. p values stem from student's t-test and refer to observed rates, not corrected rates. Numbers in () represent 95% Confidence Interval. Reference always refers to the same months in the respective years. * Complicated cases were defined as any procedure including ostomy or the need for revision surgery. Absolute numbers in Supp. Table 2. Corrected values were calculated on the basis of the average annual change between 2012 and 2019. This average annual change was applied to the value of respective months of 2019 to evaluate an estimate for 2020 in assumption of a linear trend. This estimation was compared to the observed rate resulting in a corrected change. In case of mortality and ostomy, due to lower absolute numbers, three decimals are provided to avoid rounding bias
