Table 4 Risk factors for hospital death, present at severe sepsis diagnosis. Model 1 shows the risk factors that were independently associated with hospital death. Model 2 shows the results of a second multivariate analysis introducing the each of the variables that make up the LODS score separately

3.14

1.51 to 6.54

   McCabe score (for each point)

1.72

1.25 to 2.37

   Chronic alcohol abuse

2.92

1.01 to 8.93

   Total LODS day 0 (for each point)

1.37

1.24 to 1.51

   Urinary tract origin of sepsis (pulmonary origin = 1)

0.09

0.02 to 0.52

Model 2:

   Age (< 45; 45 to 80; > 80)

4.04

   McCabe score (for each point)

1.68

1.21 to 2.34

   Neurological LODS (for each point)

1.88
