Table 2 Quartile estimates of the probability of achieving muscle strength above the ICU-AW cutoff, defined as below 7.0 kg for women and 11.0 kg for men, measured from the moment of ICU admission and the first strength measurement.
| Time | Percentile | Estimated time (days) | 95% LCI | 95% UCI |
|---|---|---|---|---|
| From ICU admission | 25 | 5 | 5 | 6 |
| 50 | 13 | 11 | 21 | |
| 75 | 41 | 30 | 66 | |
| From the first strength measurement | 25 | 1 | – | – |
| 50 | 1 | 1 | 4 | |
| 75 | 33 | 19 | 74 | |
| LCI – lower 95% confidence interval; UCI – upper 95% confidence interval. | ||||
