Table 2 Summary of glycemic control studies

Thiele RH 2009 [52]

Single-center

Before–after study

Patients with the primary diagnosis of SAH

5.0–6.7 mmol/l

(90-120 mg/dl)

N = 491

No detail described

N = 343

In-hospital mortality

Three was no significant difference in in-hospital mortality.

Latorre JG 2009 [53]

Single-center

Before–after study

SAH patients with blood glucose > 11.1 mmol/l (200 mg/dl) on admission or the first 24 h mean blood glucose > 7.8 mmol/l (140 mg/dL)

4.4–7.8 mmol/l

(80-140 mg/dl)

N = 166

≦ 11.1 mmol/l

(200 mg/dl)

N = 166

mRS ≧ 4 at 3–6 months

Given temporal trend, there was no significant difference in neurological outcome.

4.4–12.2 mmol/l

(80–220 mg/d)

N = 38

mRS ≧ 4 at 6 months (as secondary outcome)
