  1. CL, cumulative load including all events; CL-I, cumulative load including only independent events; CL-NoBP, cumulative load excluding events related to the disorder. aExponentiated coefficients, representing the hazard ratio. bRobust standard error (SE), corrected for the dependency of multiple times to event within the same subject.
