The scatter plot of intracranial pressure (ICP) and the mean optic nerve sheath diameter (ONSD-mean) of both eyes and intracranial pressure and the body mass index. ICP was significantly associated with the mean ONSD (r = 0.61, P < 0.001) (a) and BMI (r = 0.55, P < 0.001) (b), not associated with age (r = −0.131, P = 0.174) (c) or gender (r = 0.03, P = 0.753) (d). In Fig. D,1 is male, 2 is female
