From: Multifocal electroretinography changes in patients on ethambutol therapy
Box and whisker plots with individual values of (a) the N1 and (b) P1 mfERG response amplitude in the ethambutol and control groups. The boxes display the values from the lower to upper quartile and the bold horizontal lines represent median values. The error bars represent the minimum-to-maximum value excluding the outliers. No significant difference was found between the ethambutol and control groups for all ring eccentricities (P>0.05).
