May One-Cup-Size Increase Be Used as the Clinical Reference?
However, we take the conclusion that “130 to 150 cc equates to a one-cup-size increase” with some reservations. Not only the statistical analysis but also the market share aroused our curiosity. In the laboratory arm, the brand and style of bra were fixed, which limited the sample capacity. Because all women did not wear exactly the same brand and type as the authors chose, they should have used median instead of mean to represent the interval increase, inasmuch as it varied between bra cup sizes, and the data might not follow a normal distribution.
In my opinion, the one-cup-size increase failed to be the clinical reference that is used to predict the breasts’ postoperative outcome. The bra cup size ranged because of the difference of brands, sizes, and bands.2 To be exact, the conclusion drawn by the author should have been, “Bra cup size has no standardization in the bra manufacturing industry.” Choosing the implant by means of the one-cup-size increase in volume seems fantastic, but may not be realistic.
