Fig. 6

The \(\:\alpha\:\) and \(\:\beta\:\) values of an IOC-MT in the external validation under 4 h gap. Each subplot was for an organ system. The left half of each subplot was the sample proportion in each \(\:\beta\:\) group, and the right half was the average attention weights in each \(\:\beta\:\) group. For intuitive presentation, we used the abbreviation of organ to replace the mathematical symbol of attention weight. For instance, ‘Coag-> Resp’ represented the attention weight \(\:{\alpha\:}_{21}\) which indicated the importance of coagulation system for predicting respiration function
