Table 2. Pearson correlation analysis between the femur length and other femoral parameters. The highest positive correlation exists between the head diameter with neck diameter. Femur length is positively correlated to a varying degree with head diameter, foveal depth, neck diameter, and neck thickness, where a statistically significant correlation can be understood by the respective p-value <0.05.
* Correlation is significant at the 0.05 level (2-tailed). ** Correlation is significant at the 0.01 level (2-tailed).
