Figure 2.

Cumulative percent of hospitalization that had each of the health-related exposures prior to hospitalization. Percentages are broken down for all Clostridioides difficile infection (CDI) cases, secondary CDI cases, secondary CDI cases with a length of stay >3 days, and for hospitalizations without CDI. For each of the exposures and each time period prior to hospitalization, CDI cases were much more likely to have a given exposure regardless of CDI case definition. Counts correspond to all possible hospitalizations (ie, we do not restrict counts to 1 hospitalization per patient).
