Adjusted effect of age on PTSS-10 score. The solid line indicates the predicted PTSS-10 score based on a patient's age after adjustment using multiple linear regression for APACHE II score, gender, cumulative lorazepam dose, and days of delirium. The dashed lines indicate the 95% confidence interval for the regression line. P = 0.04 for the effect of age and p = 0.04 for non-linearity, indicating PTSS-10 scores increase as age increases up to 50 years, after which PTSS-10 scores decrease as age increases.
