From: Radiographic vertical tracheal diameter assessment at different levels along the trachea as an alternative method for the evaluation of the tracheal diameter in non-brachycephalic small breed dogs

Fig. 2

Box-and-whisker plots of the tracheal diameter (A), manubrium tracheal index (B), thoracic inlet tracheal index (C), and proximal rib3 tracheal score (D) at levels A, B, and C along the trachea for non-brachycephalic small breed dogs (n = 81) with no clinical or radiographic evidence of respiratory or cardiovascular diseases. Boxes and whiskers represent the 25th to 75th percentiles and ranges, respectively; the lines and crosses within boxes represent the medians and means, respectively
