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

Table 3

Three-layer networks and number of support vectors for Brief Pain Inventory (BPI) scores in artificial neural network (ANN) and support vector machine (SVM) models.

Subscales	ANN-based model*	SVM-based model^#
Worst pain	11-5-1	143
Average pain	11-7-1	93
Present pain	11-5-1	119
Aggregated pain interference	11-4-1	127

∗Values are for input layer-hidden layer-output layer.
#Values are numbers of support vectors.
