The subgroup analysis indicated a significant association between DII and all-cause mortality among dermatitis patients with HTN, one of the reasons for this result might be that, compared with the general population, HTN patients have higher levels of serum inflammatory markers, including CRP, high-sensitivity CRP, fibrinogen, and IL-6, which are also associated with target organ damage and the risk of future cardiovascular events (99). This evidence concerns the gene IL6 and dermatitis.
