Fig. 5From: Comparability of three intraocular pressure measurement: iCare pro rebound, non-contact and Goldmann applanation tonometry in different IOP groupBland–Altman plot of means against the difference between the IOP measured by NCT, iCare pro and GAT in four IOP groups. NCT vs iCare pro: horizontal panel a-d; iCare pro vs GAT: horizontal panel e-h; NCT vs GAT: horizontal panel i-l; low IOP group: vertical panel a, e, and i; normal IOP group: vertical panel b, f and j; moderate elevated IOP group: vertical panel c, g and k; higher IOP group: vertical panel d, h and lBack to article page
