Figure S2 | Relationship between loge citation frequency (y) and loge citation value (x) for 60 researchers within the discipline of ophthalmology. Each light grey, dashed line is the linear (on the loge-loge scale) fit for each individual researcher. The area under the fitted line (Arel) is shown for individual 32 (ID32; red horizontal hatch) and individual 27 (orange vertical hatch).
