The insulin sensitivity allele score ( GS-InSens ) was positively associated with spontaneous postnatal weight gain ( regression coefficient -LSB- B -RSB- : @ SD scores per allele ; @ % confidence interval -LSB- CI -RSB- , @-@ @ ; P = @ ) and also in response to GH therapy with first-year height velocity ( B : @ cm/y per allele ; @ % CI , @-@ @ ; P = @ ) and change in IGF-@ ( B : @ SD scores per allele ; @ % CI , @-@ @ ; P = @ ) .
