Figure 2From: A path analysis of the effects of the doctor-patient encounter and expectancy in an open-label randomized trial of spinal manipulation for the care of low back pain Path analysis diagram. Standardized path coefficients are presented. The absolute magnitude indicates the strength of the relationship between variables and the arrow points to the presumed direction of influence. Solid arrows indicate statistical significance (p < .05) and the width of solid arrows indicates the magnitude of the coefficient. Color of the arrow indicates variable of origin; green = pain, red = DPE, blue = expectations, black = treatment dose.Back to article page
