From: Noninvasive intracranial pressure estimation by orbital subarachnoid space measurement: the Beijing Intracranial and Intraocular Pressure (iCOP) study

Figure 5

Bland-Altman graph of the inter-method agreement of the non-invasive magnetic resonance imaging (MRI) derived intracranial pressure (ICP) assessment using weighting function (1) (A), (2) (B), and (3) (C) and invasive lumbar cerebrospinal fluid pressure (CSF-P) measurements in the test group. CSF-P, cerebrospinal fluid pressure; ICP, intracranial pressure; SD, standard deviation. The solid line represents the mean of the difference between both methods; the two dashed lines represent the mean of the difference plus or minus the 1.96-fold standard deviation of the difference.
