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).
