Comparisons of Prediction Models of Myofascial Pain Control after Dry Needling: A Prospective Study

Table 5

Global sensitivity analysis of artificial neural network (ANN) model in predicting Brief Pain Inventory (BPI) scores.

ANN model	Rank 1st	Rank 2nd	Rank 3rd	Rank 4th
	VSR	VSR	VSR	VSR
Worst pain	Pretreatment worst pain score; (5.83)	Sleep deprivation; (1.74)	Pain duration; (1.43)	Nutritional deficiency; (1.24)
Average pain	Pretreatment average pain score; (5.51)	Sleep deprivation; (1.66)	Pain duration; (1.52)	Nutritional deficiency; (1.44)
Present pain	Pretreatment present pain score; (5.15)	Sleep deprivation; (1.60)	Pain duration; (1.20)	Nutritional deficiency; (1.18)
Aggregated pain interference	Pretreatment aggregated pain interference score; (6.07)	Pain duration; (1.57)	Sleep deprivation; (1.44)	Nutritional deficiency; (1.30)
