20 Another research indicated that there was a modest causality for psoriasis on type 2 diabetes ( p = 1.6E4, OR = 1.01), and a nominally significant causality for type 2 diabetes on psoriasis ( p = 0.014, OR = 1.05). 21 Considering that psoriasis was a systemic inflammatory disease, FI seems to be more reasonable and clinically relevant than a single factor to assess psoriasis risk, which has been applied in skin cancer. 22 The underlying mechanism by which FI increases the risk of psoriasis remains unclear.
