We thank Parker and Wright for engaging in this roundtable debate in such a spirited way. The ‘Pharmacogenetic [test] to Avoid Loss of Hearing’ Trial is the first time a genetic point of care test has been applied in the acute neonatal setting; therefore, it is not surprising that questions have been raised which require debate, discussion and clarification. Parker and Wright misattribute several assumptions to the roundtable authors, which we would like to clarify here. Since they raise wider questions (...) about the PALOH trial itself, several of the roundtable discussants have made a joint response. (shrink)
