In the multivariate logistic regression, poor oral intake (odds ratio [OR] = 5.87, 95% confidence interval [CI]: 2.42–8.25, p = 0.002), lymphadenopathy (OR = 7.20, 95% CI: 6.24–11.76 p < 0.001), mean ambient temperature ≥ 20 °C (OR = 4.60, 95% CI: 1.46–10.28, P = 0.016), neutropenia (absolute neutrophil count [ANC] ≤ 2000 cells/μL) (OR = 8.95, 95% CI: 2.30–21.25, p = 0.005), C-reactive protein (CRP) ≤ 1.2 mg/dL, (OR = 6.42, 95% CI 4.02–24.21, p < 0.001), and creatinine kinase (CK) ≥ 200 IU/L (OR = 5.94, 95% CI: 1.42–24.92, p = 0.015) were significantly associated with the SPG group (Table 3). This evidence concerns the gene CRP and Lymphadenopathy.
