Table 1 presents a comparison of demographics and clinical characteristics between the MSSA and MRSA groups. No significant differences were observed in the distribution of clinical presentations or affected joints between the two groups. Laboratory findings upon admission also showed similarities, including levels of CRP, ESR, and white blood cell count (WBC) in both serum and synovial fluid. However, hospital-acquired infection was more prevalent in the MRSA group (17.9% vs. 1.6%, p = 0.005). The gene discussed is CRP; the disease is nosocomial infection.
