Trial profile. The total number of women at admission was 34. The total number of months of follow-up was 1,125. Two patients were lost to follow-up (one at 3 months and one at 19 months). Four women expelled the LNG-IUS (at day 2 and at month 1, 3, and 15). Two women underwent premature removal (at month 7 and 16). At the end of the study (36 months), there were 24 women. Two women participated less than 36 months but still had follow-up at 24 and 30 months, respectively. IUSs in four women were removed at the end of the study (at 36, 44, 48, and 52 months). Ten subjects were followed-up more than 48 months.

3. FIGURE 2
Changes of MBL before and after LNG-IUS insertion. Changes of MBL of each individual are expressed in the linear graphs, with dots indicating the MBL value at pretreatment cycles (−2 months and −1 month) and at 6, 12, 24, and 36 months of follow-up. MBL decreased markedly at 6 months in all women. In one case (---), MBL was very high before treatment (259.6 and 150 mL) and decreased to 100 mL at 12 months; thus, it remained higher than the limit of menorrhagia, but the patient became amenorrheic after 24 months.
