| Surgery | No Surgery | P Value | |
|---|---|---|---|
| LFSC size (mean) (SD) (mm) | 10.5 (3.9) | 9.5 (3.3) | .32a |
| MRI signal intensity (No.) (%) | .07b | ||
| High T2 with a thin rim | 11 (48) | 24 (78) | |
| High T2 with a thick rim | 11 (48) | 6 (19) | |
| Low T2 | 1 (4) | 1 (3) | |
| CT characteristics (No.) (%) | .003b | ||
| Calcified | 12 (48) | 4 (12) | |
| Not calcified | 13 (52) | 28 (88) |
a
P value based on the 2-sample t test of the difference between means.
b
P value based on a χ2 test of the difference in proportions.
