TNF and Hypertension: Interestingly, only in the chronic CSC group, individuals with systemic hypertension had higher median (IQR) plasma levels of IL‐8 [2.95 pg/ml (2.53–3.47) versus 1.56 pg/ml (1.34–2.06); p = 0.005], IL‐6 [3.6 pg/ml (3.1–4.5) versus 2.1 pg/ml (1.4–3.0); p = 0.033] and TNF‐α [4.09 pg/ml (4.09–4.25) versus 3.33 pg/ml (2.95–3.79); p = 0.001], as compared with those without hypertension.
