Table 5 Association between levels of pain intensity according to MRI finding (n = 70)

From: Shoulder adhesive capsulitis: can clinical data correlate with fat-suppressed T2 weighted MRI findings?

MRI finding Pain intensity Test value p-value
Absent, minimal + mild pain (n = 28) Moderate and severe pain (n = 42)
