3.7. Assessment of inconsistency

Skin grafting can be classified into multiple types, and there are various of intervention measures for VLUs in studies. In the direct evidence and indirect evidence network of each outcome indicator, the node-splitting model will be used to test inconsistency in every closed loop of evidence through Stata software.^[23] If P > .05, the consistency model is adopted; otherwise, the consistency model is adopted. For the consistency model analysis results, the inconsistent model's stability can be tested by the inconsistent model when the inconsistent model factors include 0 and the standard inconsistency deviation. When the consistent effect model's random standard deviation is approximately equal to the standard deviation of the inconsistent model, the consistency model results are more stable and reliable.
