Comparison of the efficiency between the IDet and NPH groups after 3 months of treatment (means ±SD)
| Variable | IDet | NPH | T/Z | P value |
| HbA1c (%) | 5.66±0.83 | 5.80±0.81 | 1.313 | 0.191 |
| Difference of HbA1c (%) | 0.77±1.53 | 0.68±1.08 | 0.331 | 0.740 |
| Days of FPG and preprandial blood glucose reaching the target (day) | 4.96±3.20 | 7.06±2.94 | 5.294 | <0.001 |
| Days of blood glucose reaching the target throughout all day (day） | 6.94±3.99 | 10.82±2.63 | 8.883 | <0.001 |
FPG, fasting plasma glucose; IDet, insulin detemir; NPH, neutral protamine Hagedorn.
