Figure 5From: Objective classification of different head and neck positions and their influence on the radiographic pharyngeal diameter in sport horsesScatter diagram of the radiographic pharyngeal diameter as a function of the ground angle at rest. There was a significant correlation between the radiographic pharyngeal diameter and the ground angle at rest (shown in Figure 1). With a polynomial trend line up to the power of two, R2 = 0.58 was achieved.Back to article page
