Comparison of patient characteristics and clinical outcomes of post-viral pneumococcal pneumonia and primary pneumococcal pneumonia.

*Patients who are immunocompromised due to either medications or immune disorders including human immunodeficiency syndrome.†Patients who have asthma, chronic obstructive pulmonary disease, or bronchiectasis.‡Patients who have heart failure, cardiomyopathy, or anther chronic condition affecting cardiac function.§Patients who have either chronic hepatitis or cirrhosis; chronic hepatitis was defined as an elevation of serum transaminases above 1.5 times of upper normal limit for longer than 6 months, and cirrhosis was defined by the presence of biochemical and radiological findings consistent with cirrhosis.¶Patients who have either nephrotic syndrome or chronic renal failure.IQR, interquartile range.*因药物或免疫紊乱类疾病（包括人类免疫缺陷综合征（human immunodeficiency syndrome））导致免疫功能低下的患者。†伴有哮喘、慢性阻塞性肺疾病或支气管扩张症的患者。‡存在心力衰竭、心肌病或其他影响心功能的慢性疾病的患者。§伴有慢性肝炎或肝硬化的患者；其中慢性肝炎定义为血清转氨酶升高至正常上限1.5倍以上且持续时长超过6个月，肝硬化则以符合肝硬化的生化与影像学表现作为确诊依据。¶伴有肾病综合征或慢性肾衰竭的患者。IQR，即四分位间距（interquartile range）。
