Compared with survivors, more non-survivors were found among older people (median age 66.0 years vs 56.0 years, p < 0.0001), male (68.4% vs 49.7%, p = 0.0003), patients with a past medical history (48.3% vs 31.2%, p = 0.0005). In terms of past medical history, cerebrovascular disease (6.1% vs 1.8%, p = 0.0098) was significantly higher in non-survivors than in survivors. In non-survivors, the percentages were higher in patients having CRB-65 score of 3–4 and FBG ≥7.0 mmol/l at admission (Table 1).
