Fig 5. Improvement of menorrhagia in the blood supply subgroups.

Fig 5a shows the percentages of improvement in menorrhagia at the short-term follow-up, including 70.5% (134/190) in the equal subgroup and 73.0% (27/37) in the unequal subgroup. Fig 5b shows the percentages of improvement in menorrhagia at the long-term follow-up, including 68.0% (100/147) in the equal subgroup and 73.9% (17/23) in the unequal subgroup. No statistically significant differences were observed between the equal and unequal subgroups at either the short- or long-term follow-up.
