A study of glycemic variability in patients with type 2 diabetes mellitus with obstructive sleep apnea syndrome using a continuous glucose monitoring system

Table 3 Comparison of the Glycemic variability indices and AHI in the study population

VARIABLE	Group A (n = 20) Mean ± SD	Group B (n = 20) Mean ± SD	Group C (n = 10) Mean ± SD	Group D (n = 10) Mean ± SD

Time in Range (%)	67 ± 4.26	69 ± 3.54	89 ± 2.71	97 ± 1.33
Time above Range (%)	20 ± 2.5	19 ± 2.8	8 ± 1.2	0
Time below range (%)	13 ± 2.1	12 ± 1.8	3 ± 1.4	2 ± 0.5
Mean Glucose (mmol/L)	7.77 ± 2.42	6.81 ± 2.31	5.85 ± 2.10	4.83 ± 1.95
SD (mmol/L)	2.44 ± 1.10	1.91 ± 0.86	0.87 ± 0.16	0.68 ± 0.11
CV (%)	31% ± 4.5	28% ± 3.5	16% ± 2.8	14% ± 2.4
Night Mean glucose (mmol/L)	6.84 ± 1.82	6.70 ± 1.64	5.05 ± 0.20	4.70 ± 0.15
Night SD (mmol/L)	2.54 ± 1.76	1.96 ± 0.92	0.98 ± 0.14	0.74 ± 0.14
Night CV (%)	37 ± 2.5	29 ± 2.3	19 ± 1.2	15 ± 1.1
MAGE (mmol/L)	5.20 ± 2.15	2.67 ± 1.04	2.47 ± 0.42	0.77 ± 0.19
NMAGE (mmol/L)	5.78 ± 2.16	2.22 ± 1.00	2.85 ± 0.42	0.62 ± 0.15

One way ANOVA applied, data failed normality hence Kruskal Wallis test applied
P value was significant between all four groups
P < 0.05 was considered significant
Time in Range: 3.9 to 10 mmol/L, Time Below range: < 3.9 mmol/L, Time above range > 10 mmol/L
