Table 4 Oxygen saturation at entry point and ferritin level in COVID-19 pneumonia cases (n = 1000)
Oxygen saturation | Normal ferritin level (n = 320) | Abnormal ferritin level (n = 680) | Analysis |
|---|---|---|---|
> 90% (n = 210) | 110 | 100 | Chi test value 60.37 p < 0.00001 |
75–90% (n = 490) | 150 | 340 | |
< 75% (n = 300) | 60 | 240 |
