Magnitude of classification 2 impacting symptom recurrence of
FUAS group
In the cox regression, age (HR=0.935, 95% CI 0.888~0.984, P=0.010) and
classification 2 (subtype II vs. other subtypes) (HR=2.315, 95% CI
1.219~4.560, P=0.011) were associated with the recurrence of
adenomyosis in FUAS group (Table 3). However, no significant
associations were found in uterus volume, lesion volume, uterus
position, lesion position, subcutaneous fat thickness, the rates of
endometriosis, and FUAS parameters (total ablation time, sonication
time, average sonication power, sonication energy, sonication volume,
NPV ratio) (P>0.05). K-M curve showed medium recurrence time in
extrinsic subtype of FUAS group (45.2 months) was shorter than that in
other subtypes of FUAS group (52.0 months) (Figure 1, P=0.032).
