Article	Design	Patient	Intervention or exposure	Comparison	Outcome	Main results
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.
