In this Article, the Supplementary Table 7 iCLUSTER output column included incorrect cluster labels for the integrated subtypes presented in Fig. 5c. These changes affect only the iCLUSTER output column and do not affect the analysis or the conclusions of the work. The authors apologise for the error. Supplementary Table 7 has been corrected online, and the original incorrect table is provided as Supplementary Information to this Amendment for transparency.
