The odds ratio of death within 1 day of a moderate (K ≥ 5.5 and < 6.0 mg/dl) and severe (≥ 6.0 mg/dl) hyperkalemic event in the study population stratified by stage of CKD. Normokalemia (K < 5.5 mg/dl) and no CKD is the reference group. P < 0.001 for all moderate and severe hyperkalemia groups, and p < 0.05 for Stage 5 with normokalemia versus reference group.
