*
3 women had 7 fibroids and 1 woman had 8 fibroids. Ultrasonographers recorded measurements for only the 6 largest fibroids detected.
†
174 fibroids included in the analysis; 4 fibroids were not visualized in all three planes (questionable fibroids) and were excluded from final analysis.
‡
Fibroid size was calculated by taking the mean diameter from all three planes (longitudinal, transverse, and anterior-posterior) The maximum mean diameter from the three planes is the diameter used to determine size.
