^b Values in bold indicate that the diagnosis was among the top 10 for that column.
^c Diagnosis is among the top 10 primary diagnoses for those alive at discharge and those dead at discharge.
^d P < 0.05 comparing proportions among hospitalizations ending in death versus those not ending in death.
