Impact of Negative Fluid Balance on Mortality and Outcome of Patients with Confirmed COVID-19

Figure 1

The area under the ROC curve for fluid balance as a classifier of mortality was 76.5 (95% CI: 71.2, 81.2). A fluid balance level of >−430 mL was associated with mortality, with a sensitivity of 68.8% (95% CI: 61.5, 74.5), a specificity of 73.5% (95% CI: 63.2, 81.4), a positive likelihood ratio (LR) of 2.52 (95% CI: 1.81, 3.53), and a negative LR of 0.43 (95% CI: 0.34, 0.55).
