Objectives

Narrative objectives1

We hypothesized that CPSP intensity would continue to decrease until a certain time. To test this hypothesis, we conducted a prospective observational study to clarify the nonlinear association between the elapsed time after surgery and the intensity of post-thoracotomy pain.

Other related information

To assess the nonlinear association between elapsed time after surgery and the intensity of post-thoracotomy pain, multivariable ordinal logistic regression with restricted cubic splines was used with the following factors as independent variables: age, gender, and operative time. Restricted cubic spline analysis is a way to test if the relationships between outcomes and explanatory variables are nonlinear. The three knots of restricted cubic splines were located at the 10th, 50th, and 90th percentiles.
