^†

Indicates codes used in multivariate modeling of both count and binary data.

^‡

Indicates codes used in multivariate modeling of only the binary data.

Abbreviations: Comfort Measures Only (CMO); Do not resuscitate/Do not intubate (DNR/DNI); Intensive Care Unit (ICU).

Logistic regression models using binary indicator variables indicating the presence/absence of the code of interest are reported as “Binary” whereas models using integer counts of the occurrence of each code are reported as “Count”.
