In addition, reverse analysis showed that PCa was correlated with the elevated level of adenosine deaminase, axin-1, C-X-C motif chemokine ligand 6, Flt3L, interleukin (IL)-24, and IL-33 (Beta: 1.7661, 95% CI: 0.2092–3.3229, P = .026; Beta: 1.9185, 95% CI: 0.1548–3.6822, P = .033; Beta: 1.9681, 95% CI: 0.4207–3.5155, P = .013; Beta: 1.6589, 95% CI: 0.0733–3.2446, P = .040; Beta: 2.2091, 95% CI: 0.4682–3.9500, P = .013; Beta: 1.8438, 95% CI: 0.0815–3.6061, P = 040). The gene discussed is IL33; the disease is posterior cortical atrophy.
