How effective is helmet therapy compared to other therapies?

What is being compared? Mean change of 3.85%  in CVAI* (toward symmetry) of 163 infants treated with a helmet, compared with mean change of -0.36% in CVAI of 16 infants treated without a helmet.
* CVAI is an index of the difference (in length) between the diagonal measurements used to calculate asymmetry.

What is being compared? Mean decrease of 61%  in diagonal difference of 159 infants treated with a helmet, compared with mean decrease of 52% in diagonal difference of 176 infants treated without a helmet.

Vles

What is being compared? Mean improvement in cosmetic deformity (out of 10)* of 66 infants treated with helmet therapy, and 39 infants treated without helmet therapy.
*0 = severely abnormal deformity; 10 = normal.

What is being compared? Mean change of 0.6 cm in diagonal difference of 36 infants treated with a helmet, compared with mean change of 0.2 cm in diagonal difference of 17 infants treated without a helmet.
Both groups began with a mean diagonal difference of 1.2 cm.

What is being compared? Mean improvement of 1.76 (out of 2)* of 25 infants treated with a helmet, compared with mean improvement of 0.4 of 10 infants treated without a helmet.
*1 = improvement; 2 = normal.
