The centrality of joint infection (n = 44, centrality = 0.08), resurfacing (n = 48, centrality = 0.07), cementing (n = 47, centrality = 0.06), and C-reactive protein (n = 54, centrality = 0.06) was greater than 0.05, suggesting that these keywords have greater than 0.05 centrality in the artificial joint infection field of importance. The gene discussed is CRP; the disease is infection.
