Relationship between glycemic variability and cognitive function in lacune patients with type 2 diabetes

Table 2 Comparison of blood glucose variability indicators in different cognitive function groups

Group	Number	SD	%CV	LAGE	TIR
Cognitive dysfunction	37	3.15 ± 0.53	31.28 ± 5.38	10.35 (6.51, 13.49)	47.04 (37.61, 53.52)
Normal cognitive function	107	2.84 ± 0.44	26.29 ± 4.83	10.01 (6.34, 12.27)	56.02 (45.78, 69.46)
Statistical parameters		-3.513	-5.254	-0.738	3.825
P value		< 0.001	< 0.001	0.461	< 0.001

SD: Standard deviation; %CV: Percentage coefficient of variation; LAGE: The largest amplitude of glucose; TIR: Time in range.
