  1. After treatment for one week, the D-D level decreased significantly with treatment in both the GMPP and RMPP groups (P < 0.05). 91.4% of children had D-D levels that remained above the upper limit of normal (> 280 ng/ml) and 27.1% of children had a moderate-to-severe increase in D-D, all of which were within the RMPP group.
