Following this correction, the Author contributions section should also be corrected to include the contribution of author Nuno Coimbra as follows: “JCM, SA, MRT, and PMB conceived the U-PIK Project. JCM, SA, MRT, PMB, FCS, MJA, MJB, PB, MRD, HP, NS, ACS, JAT participated in the study design. AP, LCi, ALC, MJA, MJB, PB, NC, ASC, LCa, LCo, CF, PF, AG, JP, MP, HP, JR, NS, FCS, FS, ARS, ACS, JAT performed the experimental work involved in sample preparation, DNA extraction and PIK3CA testing and reporting. JCM, SA and MRT were responsible for analyzing PIK3CA testing data from U-PIK testers, for reporting anonymized PIK3CA testing performance back to U-PIK testers, and also for the analysis of molecular reports. JCM, SA, MRT, PMB and AP edited the manuscript, drafted and written with editorial assistance of JCS (Acknowledgements). All authors read and approved the final manuscript.”
In the published article, there was an error regarding the affiliation for Nuno Coimbra, who was erroneously excluded from the author list and should have affiliation Serviço de Anatomia Patológica, Instituto Português de Oncologia do Porto Francisco Gentil (IPO Porto), Porto, Portugal.
