Table 5. Pearson’s Correlation Coefficients between the APCI and Radiologic Parameters of Anteroposterior Coverage of the Acromion.

APCI	AT	AHI	Anterior coverage†	Posterior coverage†
Pearson’s correlation coefficient	–0.437	–0.251	0.626	0.103
p-value	< 0.001*	< 0.001*	< 0.001*	0.054

APCI: anteroposterior coverage index, AT: acromial tilt, AHI: acromiohumeral interval.
