Segmented multivariate linear regression model CSFP (mm Hg) by age and sex.
<p>For each year of increase in age, CSFP decreased 0.009 mmHg (p = 0.132) for age <50 and by 0.056 mmHg, (p<0.001) for age greater than 50. Prior to age 50, the slope is not different between males and females (p = 0.369). After age 50, the gender difference in the slope is borderline significant (p = 0.067). The r<sup>2</sup> of this model is 0.071.</p
Average intraocular pressure against age.
<p>Formula for the regression: y = −0.0144×+15.575, r<sup>2</sup> = 0.003.</p
Mean cerebrospinal fluid pressure (mm Hg) by age categories.
<p>Percent difference is compared against the 20–49 year age group.</p>*<p>
<i>P-value based on F-test of difference in CSF means between each older age category and age category 20–49.</i></p>**<p>
<i>Percentage lower of mean in age category than mean in 20–49 age category.</i></p

Intraocular pressure, cerebrospinal fluid pressure, and translaminar pressure difference by age groups.
<p>The percentage difference is calculated by mean IOP average of each age group against mean IOP average at age 20–49; significance measured by two-tailed Student's t-test. <i>IOP: intraocular pressure; CSFP: cerebrospinal fluid pressure; TLPd: translaminar pressure difference</i>.</p
