TTV DNA detection and load in plasma from critically ill COVID-19 patients stratified by occurrence of clinical events and death.
| Clinical outcome | TTV DNA-based parameter | |||
|---|---|---|---|---|
| Detection of TTV DNA in plasma during ICU stay. No. of patients (%) | Non-detection of TTV DNA in plasma during ICU stay. No. of patients (%) | TTV DNA load ≥3.3 log10 copies/ml within week 1 after ICU admission. No. of samples (%)a | TTV DNA load <3.3 log10 copies/ml within week 1 after ICU admission. No. of samples (%)a | |
| Infectious eventsb | 25 (89.2) | 3 (10.7) | 10 (45.4) | 12 (54.5) |
| No infectious eventsb | 13 (59.0) | 9 (40.9) | 4 (22.2) | 14 (77.7) |
