Time to exposure and main-diagnosis matching. This figure illustrates the time-to-exposure stratification and within-main-diagnosis approach used in the regression model. Controls are required to have a length of stay at least equal to the time of infection in days of the corresponding CDI case and be in the same main diagnosis group. Here, B, C, D and E are for instance suitable controls for A, while F–L are not, being in a different main diagnosis group (H–L) or not meeting the time-to-exposure criterion (F). Patients and main diagnosis groups here are chosen exemplary for illustrative purposes
