Table 1 The summary statistics of the horizontal distance (a) and the depth (b) from reference point X to the TDN and the distance to the LTV from the lateral border of pectoralis minor (d) (df - degree of freedom, LTV - lateral thoracic vein, reference point X - a point along the LTV, 2 cm inferior to its confluence with the axillary vein, SD – standard deviation, SE - standard error, TDN - thoracodorsal nerve)
Measured distances | Mean (mm) | SD (mm) | 95% confidence interval (mm) | Range (mm) | Skewness | Kurtosis | Shapiro-Wilk test (df = 20) |
|---|---|---|---|---|---|---|---|

Horizontal distance from reference point X to the TDN (a) | 14.5 | 8.9 | 10.3–18.6 | 2–31 | .559 (SE = .512) | −.718 (SE = .992) | .926 (p = .132) |
Depth from reference point X to the TDN (b) | 19.7 | 7.3 | 16.3–23.1 | 8–34 | −.071 (SE = .512) | −.620 (SE = .992) | .964 (p = .624) |
