Performance of the MMI system using different fusion approaches in identifying pulmonary infections types

(A) Structure diagram of different fusion strategies: early fusion, intermediate fusion, and late fusion. Further details were provided in Figure S4.

(B) Evaluation of the three fusion approaches to predict pneumonia types (average performance, bacterial pneumonia, fungal pneumonia, viral pneumonia, and pulmonary tuberculosis) in the internal testing dataset. The performance measures were visualized through boxplots representing the statistical distribution of AUCs, including maximum, minimum, median, and upper and lower quartiles of a set of data (first/third quartile) as well as outliers. A t test was used to calculate the p value between approaches: ∗∗∗∗p < 0.0001.
