Insulin-like growth factor-1 and neurologic outcomesa
| Outcome | Odds Ratio | 95% CI | P Value |
|---|---|---|---|
| Delirium risk | 1.0 | 0.6 to 1.8 | 0.97 |
| Duration of acute brain dysfunction | Nonlinearb | 0.22 | |
All associations were adjusted for age, severity of illness, and severe sepsis at ICU admission.
The relationship between Insulin-like-growth factor-1 and delirium was nonlinear; thus a single odds ratio cannot estimate this association.
