Pneumonia subtype discriminability of the machine learning model.

Disease	Positive/total	AUC, % (CI)	Accuracy, % (CI)	Sensitivity, % (CI)	Specificity, % (CI)
	N	% (95%-CI)	% (95%-CI)	% (95%-CI)	% (95%-CI)
Bacterial PNA	45/175	77.4 (70.2–84.5)	55.4 (47.7–62.9)	100.0 (92.1–100.0)	40.0 (31.5–49.0)
Viral PNA	49/175	62.9 (54.0–71.9)	56.6 (48.9–64.0)	67.3 (52.5–80.1)	52.4 (43.3–61.3)
Non PNA	62/175	62.5 (54.1–70.9)	61.7 (54.1–68.9)	38.7 (26.6–51.9)	74.3 (65.3–82.1)
