A dataset containing anonymized real life human subjects data on eyes with treatment naive neovascular age-related macular degeneration (AMD), which underwent intravitreal anti-VEGF therapy with ranibizumab and/or aflibercept.
data("amd")A data frame with 40764 rows and 7 variables:
Anonymized patient identifier
Left or right eye of patient (0 = right, 1 = left)
Days after date of first appointment (0 = first appointment)
Age (years) at day of first appointment
Gender of patient (0 = male, 1 = female)
Visual acuity in Early Treatment Diabetic Retinopathy Study letters
Current number of injection at appointment date
Note there are erroneous visual acuity entries in this data set which I noticed during the work on this package. The data set curator has been contacted and it it was concluded that these were erroneous entries in the original medical health records. I decided to keep the values in the data set and wait for the final decision how to proceed from the data set curator (if they are going to replace it with missing values or not). I believe this is a great example for the challenges of real life data and a reminder to remain vigilant when doing data analysis.
The data was collected in Moorfields Eye Hospital, London, UK. (Information governance sign off Moorfields Eye Hospital 19/07/2018)
