Thanks for your response Niki!
Does biochemical occurrence require that the BCR_Event (col AB) contain a "BCR_Algorithm" value?

The Portal uses the BCR (biochemical recurrence) data for survival analysis, so only the columns labeled BCR_FreeTime and BCR_Event (AA and AB).

I've downloaded the attached clinical annotation file from Barry Taylor's paper. This data is utilized by your website to derive survival curves. Can you tell me what columns are used for your KM survival plots? If months disease free is equal to months survival is it not used in your survival plot? Are only samples with a "BCR_Algorithm" value in the BCR_Event (column AB) used in survival plots?
