Figure 2 Box-and-whisker plot illustrating the relationship between mean follicle diameter classes and actual follicle (follicular fluid volume), VOCAL, and SonoAVC volume measurements. Horizontal lines inside the boxes represent median levels. Upper and lower limits of the boxes and whiskers represent the 75th and 25th centiles and 90th and 10th centiles, respectively. Mean follicle diameters were arbitrarily sorted into eight different groups: A, 12.0 to 12.9 mm (n = 2); B, 13.0 to 13.9 mm (n = 5); C, 14.0 to 14.9 mm (n = 13); D, 15.0 to 15.9 mm (n = 6); E, 16.0 to 16.9 mm (n = 9); F, 17.0 to 17.9 mm (n = 6); G, 18.0 to 18.9 mm (n = 9); and H, 19.0 to 19.9 mm (n = 9). Follicles measuring ≥20 mm in diameter (n = 13) were not included in the analysis. Note the poor correspondence between mean follicle diameters and follicle volumes irrespective of the assessment approach employed.
