Observer 1Observer 2Observer 3
Summary of the difference between the observers for the estimation of CDR by monoscopic viewing. Mean diffs: mean differences are shown for CDR assessments at matched 10 degree intervals. SD diff: standard deviation of the difference between measurements. ICC: intraclass correlation coefficient. *Intraobserver comparison. †Interobserver comparisons.
