The white blood cell (WBC) count (5.8 ± 1.6 vs. 6.5 ± 1.5, P < 0.001), neutrophil count (3.6 ± 1.3 vs. 4.0 ± 1.2, P < 0.05), C-reactive protein (CRP) level (2.3 ± 1.5 vs. 3.1 ± 2.6, P < 0.05) and platelet-to-lymphocyte ratio (PLR) (89 ± 21 vs. 102 ± 41, P < 0.05) were all significantly higher in patients with hypokalemia than in those with normokalemia (Table 4). The gene discussed is CRP; the disease is Hypokalemia.
