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

Table 2

Coefficients of significant variables for Brief Pain Inventory (BPI) scores in multiple linear regression model after dry needling.

	Worst pain		Average pain		Present pain		Aggregated pain interference*

Age	−0.03	0.041	−0.04	0.045	−0.03	0.044	−0.05	0.029
Pain duration	0.28	<0.001	0.01	0.021	0.03	0.037	0.01	0.035
Gender (female versus male)	−0.51	0.036	−0.64	0.023	−0.69	0.031	−0.71	0.030
Marital status (single versus married)	0.54	0.039	0.67	0.014	0.68	0.014	0.59	0.038
Sleep deprivation (yes versus no)	1.53	<0.001	1.14	<0.001	0.98	0.012	1.06	<0.001
Nutritional deficiency (yes versus no)	1.82	<0.001	1.60	0.018	1.90	<0.001	1.71	0.001
Pretreatment BPI score	0.58	<0.001	0.34	<0.001	0.46	<0.001	0.28	<0.001

∗Aggregated pain interference was calculated as follows: [(pain interference of general activity + mood + walking ability + normal work + relationship + sleep + enjoyment of life)/7].
