Change in Humphrey visual field mean deviation from baseline, at follow-up. Each point represents a single patient’s change in Visual Field Mean Deviation from baseline, with baseline taken from Humphrey Visual Field conducted at last visit prior to trabeculectomy. A line of best fit obtained from linear regression (maximum likelihood) is shown, with 95% confidence bands. The equation of the line of best fit, along with the R2 value, which indicate goodness of fit, is shown in the legend.
