Mammary asymmetry was estimated visually by different investigators in three series of scoliotic girls and in three control groups. The breasts of each girl were classified as being equal in size or as being obviously different in size, note being made of which breast was the larger. Breast asymmetry was significantly more common among the scoliotic than the normal girls. Moreover, the left breast was significantly more often larger in the scoliotic series of girls. On the other hand, there was no significant difference in the frequency of breast asymmetry in respect of the classifications according to curve type (right convex thoracic vs. other types) and to Cobb angle (35 degrees or less vs. more than 35 degrees).
不同研究人员对三组脊柱侧弯女童和三个对照组的乳腺不对称情况进行了目测评估。将每个女童的乳房分为大小相等或明显不等，并记录哪侧乳房较大。脊柱侧弯女童中乳腺不对称的情况明显比正常女童更为常见。此外，在脊柱侧弯女童组中，左乳较大的情况明显更为常见。另一方面，根据侧弯类型（右凸胸弯与其他类型）和Cobb角（35度及以下与超过35度）分类，乳腺不对称的发生率没有显著差异。
