Table 2. Comparison of the aspects related to continuous dialysis between survivors and non-survivors.
| Variables | Survivors (78) | Non-survivors (105) | Total (183) | P value |
|---|---|---|---|---|
| Dialysis prescribed dose (mL/kg/h) | 37.6 (33–45.1) | 38 (33.7–43.2) | 37.9 (33.4–43.9) | 0.86 |
| Dialysis delivered dose (mL/kg/h) | 32.8 (28.8–40) | 33.6 (29.3–38.5) | 33.2 (28.9–38.7) | 0.88 |
| Interruption time during CVVHDF (hours) | 1 (0–8.6) | 2 (0–15.8) | 2 (0–10) | 0,21 |
| Number of days on CVVHDF | 5 (3–8) | 7 (3–12) | 6 (3–10) | 0.45 |
| Time from ICU admission to starting time of CVVHDF (days) | 1 (1–3) | 2 (1–4) | 2 (1–4) | 0,01 |
| Percentage change of weight from hospital admission to beginning of CVVHDF (%) | 5.62 (0.82–12.13) | 8.11 (0.95–17.97) | 7.1 (1.0–15.4) | 0.15 |
| Fluid balance (cumulative) during dialysis (L) | -4.13 (-7.78–-0.77) | +0.65 (-3.68–+5.23) | -1.84 (-5.74–+ 2.99) | <0,001 |

CVVHDF, continuous venovenous hemodiafiltration; ICU, intensive care unit. Categorical variables described by absolute value (percentage) and numeric variables described by median (IQR).
