From: Association of depression and hydroxyurea use with neuropathic pain in hemoglobinopathies
Comparison of DN4 neuropathic pain scores (0–10 scale) between patients with and without hydroxyurea treatment. Neuropathic pain scores were significantly higher in patients receiving hydroxyurea therapy, and correlation analysis confirmed a moderate positive association between hydroxyurea use and DN4 scores (rs = 0.363, p < 0.01). Diamonds represent outliers beyond the interquartile range.
