Table 4 Variables included in the Cox proportional hazards survival model and hazard ratios of patients who developed hypophosphatemia during the continuous veno-venous hemofiltration therapy period a

From: Hypophosphatemia during continuous veno-venous hemofiltration is associated with mortality in critically ill patients with acute kidney injury

Characteristics Odd ratio (95% confidence interval) P
Age 1.004 (0.995 to 1.013) 0.373
Presence of chronic ill health 1.284 (0.946 to 1.742) 0.109
