There were no differences in the median (IQR) plasma levels of cytokines between patients with and without hypertension in the acute CSC group [IL‐8: 1.69 pg/ml (1.29–3.09) and 1.67 pg/ml (1.19–1.99), p = 0.830, respectively; IL‐6: 2.2 pg/ml (2.00–3.1) and 2.2 pg/ml (1.5–2.6), p = 0.635, respectively; TNF‐α: 3.18 pg/ml (2.57–4.09) and 3.03 pg/ml (2.57–3.79), p = 0.846, respectively]. Here, IL6 is linked to hypertensive disorder.
