Percentages of responses supporting inclusion of each variable as part of a minimum dataset are given, along with the recommended frequency of repeat assessment. Where 100% agreement is reached, the variable was included in the registry as part of the minimum dataset.
EDT, electrodiagnostic testing; FAF, fundus autofluorescence.
