  1. This table summarizes a total of six GLM regression analyses, each using a gamma distribution and a log link function. Each cell gives the effect of CDI infection on the respective outcome on the left from different GLM regressions. All regressions use a within-main-diagnosis estimation and control for comorbidities according to Resch (2008), for age, age2, and for sex. Regressions in the second column additionally apply a time-to-exposure stratification. 95% confidence intervals are in brackets
