Table 2. The effect of stem cell therapy on the insulin daily requirement levels, HbA1C and peptide in different types of diabetes.

Variables	Type of diabetes	Summary estimates of mean difference 95% CI	P value	I2 (%)	Heterogeneity test
HbA1C (%)	T1DM	1.71 (0.51, 2.92)	0.005	94	3,076 (P<0.0001)
	T2DM	1.27 (0.84, 1.70)	<0.0001	88	68.80 (P<0.0001)
C-peptide (ng/mL)	T1DM	−0.25 (−0.45, −0.05)	0.01	98	711.18 (P<0.0001)
	T2DM	−0.13 (−0.96, 0.70)	0.76	99	630.14 (P<0.0001)
Daily insulin requirement (U/kg per day)	T1DM	0.07 (−0.07, 0.20)	0.35	99	833.70 (P<0.0001)
	T2DM	0.23 (0.03, 0.44)	0.02	93	44 (P<0.0001)
