Table 3 Episodes of blood glucose levels exceeding the upper limit

From: Differential temporal profile of lowered blood glucose levels (3.5 to 6.5 mmol/l versus 5 to 8 mmol/l) in patients with severe traumatic brain injury

Survival status Parameters Blood glucose 3.5 to 6.5 mmol/l Blood glucose 5 to 8 mmol/l
Survived Blood glucose (mmol/l; median [range]) 7.3 (6.6–14.8)* 8.7 (8.1–18.1)
  Blood glucose < lower limit (n [%]) 81/85 (95%) 89/92 (97%)
  Episodes (median [range]) 17 (2–75)* 8.5 (1–85)
  Time point of occurrence (%)   
     Week 1 55% 50%
     Week 2 24% 27%
     Week 3 21% 23%
Died Blood glucose (mmol/l; median [range]) 2.7 (0.6–3.4); NS 3.7 (3.1–3.9)
  Blood glucose < lower limit (n [%]) 28/29 (97%) 20/22 (91%)
  Episodes (median [range]) 11.5 (1–31)* 6.5 (1–61)
  Time point of occurrence (%)   
     Week 1 78%* 47%
     Week 2 16% 18%
     Week 3 6% 35%
  1. Episodes of blood glucose levels exceeding the upper limit in surviving patient and those who died within the two predefined blood glucose groups. Increased incidences in elevated blood glucose levels were predominantly encountered in the low blood glucose group during the first week. *P < 0.05, Whitney-Mann rank-sum test.
