TABLE 4.

Diagnostic performance of the scoring system for differentiating pulmonary mucormycosis from invasive pulmonary aspergillosis.

Score	PM (N = 34)	IPA (N = 60)	Sensitivity	Specificity
−13.0	94	0	100 (90–100)	0 (0–6)
−6.5	72	22	94 (80–99)	33 (22–47)
−0.5	59	35	88 (73–97)	52 (38–65)
2.5	39	55	71 (53–85)	75 (62–85)
8.0	37	57	71 (53–85)	78 (66–88)
13.5	21	73	47 (30–65)	92 (82–97)
16.5	14	80	29 (15–47)	93 (84–98)
22.5	9	85	20 (9–38)	97 (88–100)
29.0	0	94	0 (0–10)	100 (94–100)

Note: Three independent predictors were used to build the scoring system: the size of representative lesion ≥ 4 cm (a), reverse halo sign (b), and airway invasive lesion (c). The total score is the sum of the three predictors (a = score 11, b = score 17, and c = score −12). The optimal cut‐off is score of 8.0 (sensitivity 71%, specificity 78%).
