TRIT1 and chronic granulomatous disease: Logistic regression was used to explore relationships between groups and test parameters, and receiver operating characteristic curve (ROC) analysis assessed test precision.<h4>Results</h4>From our findings, the optimum cut-point for IPPT to differentiate CGD patients from healthy group with fMLP% was 0.26%, and FMLP MFI was 9.15, PMA% was 58.70%, and PMA MFI was 50.00.
