From: The association between age and acute pain sensitivity in patients with Herpes Zoster
Non-linear relationship between age and NRS-11 pain score, assessed by a generalized additive model (GAM). The solid red line represents the fitted smoothing curve, and the red shaded area indicates the 95% confidence interval. The analysis was performed using a generalized additive model (GAM) to capture the non-linear relationship between age and NRS-11 pain score. Adjustments were made for potential confounders, including albumin, CRP, gender, BMI, pain duration characteristics, cystatin C, and white blood cell count. The P-value for non-linearity was 0.631, indicating a linear relationship between age and NRS-11 score.
