The accompanying conditions of blood pressure (71 ± 13 vs 81 ± 14 mmHg, P < 0.001), mechanical ventilation (69.0% vs 28.1%, P < 0.001), oliguria (12.7% vs 3.1%, P = 0.001), hypoalbuminemia (31.1 ± 4.8 vs 35.2 ± 5.0 g/L, P < 0.001), low prealbumin level (140 vs 189 g/L, P < 0.001), anemia (106 ± 23 vs 118 ± 20 g/L, P < 0.001), hypermagnesemia (0.9 vs 0.9 mmol/L, P = 0.018), and hyperphosphatemia (1.3 vs 1.1 mmol/L, P = 0.003) of patients in the death group significantly increased compared to those in the survival group. Here, TTR is linked to anemia.
