The question should have included 'placebo', because the sentence refers to the matching of 'something'. This something is not just the 'sequencing'. The 'sequencing' of what? it has to be qualified. Whose 'sequencing? I understand, the 'placebo sequencing', So, the subject matter that has to be matched is the
'placebo sequencing'. MY logic and MY understanding!! Ι don't think the placebo gets changed sequentially!!! . The only thing that changes is the 'sequencing'.
If I were to translate the proper text sentence, I would say, 'συνδυασμένες αλληλουχίες εικονικού φαρμάκου'.

Μήπως το matching αναφέρεται στο placebo και όχι στο sequence; Υπάρχει αλλού στο κείμενο αναφορά σε matching placebo;
