Table 1 presents a comparison of baseline characteristics among patients with different levels of the Wells score. Patients in the higher Wells score group were significantly older, more likely to experience atrial fibrillation, dysphagia, had higher levels of white blood cell count (WBC), creatinine, blood urea nitrogen (BUN), blood glucose, D-dimer, NIHSS score, A2DS2 score, and pneumonia severity index (PSI) score, had lower levels of red blood cell count (RBC), hemoglobin, total cholesterol (TC), and albumin. The gene discussed is ALB; the disease is pneumonia.
