Fig. 3: Multivariable reference centiles for mGS.
From: Multivariable reference centiles for maximum grip strength in childhood to young adults

Age-, height- and BMI-adjusted reference centiles for mGS were presented for females (A) and males (B). First, the predicted GS is determined using the multiple linear regression formula presented in the figure based on age, height and BMI. Then the predicted GS and the measured mGS are entered in the corresponding reference centile.
