Accuracy of Point Scores Based on Logistic Regression Models for the Diagnosis of Acute Rhinosinusitis and Acute Bacterial Rhinosinusitis Using 3 Different Reference Standards

Reference Standard	Score Points	Sinusitis/Total No. (%)	Likelihood Ratio
Abnormal CT finding
Low risk	−2 to 1	17/43 (39.5)	0.29
Moderate risk	2 to 4	32/50 (64.0)	0.80
High risk	5 to 9	69/78 (88.5)	3.40
Total		118/171 (69.0)
Classified as low or high risk		121/171 (70.8)
Abnormal antral puncture finding
Low risk	−2 to 0	11/44 (25.0)	0.30
Moderate risk	1 to 4	53/99 (53.5)	1.10
High risk	5 to 6	23/23 (100.0)	42.00
Total		87/166 (52.4)
Classified as low or high risk		67/166 (40.4)
Positive bacterial culture
Low risk	−1 to 3	13/80 (16.3)	0.35
Moderate risk	4 to 6	35/71 (49.3)	1.80
High risk	7 to 8	11/15 (73.3)	5.00
Total		59/166 (35.5)
Classified as low or high risk		95/166 (57.2)

CT=computed tomography.

Note: Number with sinusitis and total are different from values for full data set, as cases with missing data were omitted.
