Accuracy of 8 algorithms.

	Calculation method	Calculation formula	Accuracy (%)
Main symptom weight (for the first 3 symptoms, if the disease has cooccurrence, multiply it by the weight coefficient)	Add prior probability	(for the first 3 symptoms, if the disease has cooccurrence, multiply it by the weight coefficient)	73
	No prior probability		69
	Log function form		77
	Equal probability		84.2
Main symptoms are not weighted	Add prior probability		73
	No prior probability		67
	Log function form		76
	Equal probability		83
