Compared with the subgroups without adverse events, deceased patients had a lower admitted SpO2, lower albumin (ALB), higher PASP, and higher BP (P < 0.05, Table 4 and Supplementary Table S5), patients complicated HF showed a longer activated partial thromboplastin time (APTT) and lower fibrinogen (Fbg), patients complicated with RF showed a lower SpO2, longer APTT, lower Barthel index, higher PASP, and higher BP. The gene discussed is ALB; the disease is hydrops fetalis.
