Duplicated patients between studies have been removed in two studies, UPP and UNT; the remaining unique patients are reported in brackets. All the datasets have been generated from Affymetrix technology and normalized using fRMA [51]. We consider for analysis the 13,091 unique genes common in all datasets.
