TNF and atherosclerosis: In the correlation analysis, there was no association of TNF-α levels (95% CI r = −0.3691 to 0.1883, p = 0.502), IL-6 levels (95% CI r = −0.3964 to 0.1572, p = 0.379), or IL-18 levels (95% CI r = −0.2958 to 0.2665, p = 0.914) between the patients with and without atherosclerosis.
