We found that 37 (28.68%) patients had HT, and patients with HT had higher levels of cystatin C (1.60 ± 0.90 vs. 1.35 ± 0.45; p = .038), higher white blood cell counts (9.93 ± 5.50 vs. 5.61 ± 3.21; p = .010), higher neutrophil counts (7.60 ± 5.28 vs. 5.61 ± 3.21; p = .010), higher monocyte counts (0.71 ± 0.42 vs. 0.57 ± 0.23; p = .020), lower LMRs (2.35 ± 1.27 vs. 3.01 ± 1.47; p = .018), and higher NLRs (6.86 ± 5.76 vs. 4.67 ± 4.38; p = .021) (Table 3). The gene discussed is CST3; the disease is hematocrit.
