Figure 6From: 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 withers angle at rest. There was a significant correlation between the radiographic pharyngeal diameter and the withers angle at rest (shown in Figure 2). With a polynomial trend line up to the power of two, R2 = 0.64 was achieved.Back to article page
