C-reactive protein as a non-linear predictor of prolonged length of intensive care unit stay after gastrointestinal cancer surgery

Figure 2 Non-linear relationship between C-reactive protein levels and log odds ratio of prolonged intensive care unit length of stay after controlling for potential confounding variables (age, gender, laparoscopic surgery, emergency surgery, cancer site, intensive care unit readmission, tracheotomy, continuous renal replacement therapy, and Acute Physiology and Chronic Health Evaluation II. ) (multivariate odds ratio, 95% confidence intervals and P values are shown). CRP: C-reactive protein; OR: Odds ratio; ICU: Intensive care unit.
