Demographic and Clinical Profiles
Table 1 illustrates the demographic and clinical profiles of the patients. From the multicenter data, the most common blood type was type O (36·90%) followed by type A (31·30%) and type B (26·00%), while type AB was only seen in 5·80%. The mean age was 48·97 years old (SD=14·74), and majority were female (61·45%), married (87·82%), had tertiary education (78·82%), and employed (67·23%) as non-healthcare workers (80·90%).
The most prevalent comorbidity was hypertension (40·91%), and almost a quarter were on anti-hypertensive medications. The mean peak creatinine, peak white blood cell count, and mean peak inflammatory markers were above the normal values. The mean oxygen saturation upon admission was 95·19% (SD=6·73), with most patients not requiring oxygen supplementation (69·09%). Among those with oxygen support, majority had low dose oxygen (21·64%) at a mean of 30·36% FiO2(SD=22·16). Over the course of hospitalization, oxygen support from admission did not change for most patients (68·91%).
