Figure 1

The frequency distribution of three pathogenic factors in the model. X1, X2, and X3 represent the pathogenic factors. A, B, C, and E represent the combinations of these factors that correspond to the onset of the disease, whereas D, F, G, and H represent the combinations for which the disease does not occur. “f” represents a frequency distribution of risk factors.
