Salve a tutti!
Ho difficoltà a tradurre "sinchronize" in questo contesto: "the
most valid classification criteria would necessarily synchronize
normal means across different clinical measurements."

Qualcuno può aiutarmi?

Grazie di ogni suggerimento!

Contesto (articolo di oculistica; criteri di definizione della Sindrome dell'occhio secco):

It istherefore evident that dry eye disease does not lend itself to
clear categorical distinctions, as the underlying causes of the
disease, such as androgen deficiency and inflammation, are
broadly related to ocular surface damage and a dysregulation of
the tear film. Especially for the purposes of clinical trials, the data support
the use of a composite index for inclusion criteria, since
any combination of thresholds would misclassify a reasonable
percentage of dry eye patients. Further,
because the longitudinal variability of each of the individual
tests has not been established, the values measured at a single
snapshot in time may not be consistent during follow-up visits.
A composite score tends to insulate estimates of severity
against measurement noise.
It is among the strongest validations of the objective approach
presented herein that the referent values match data
from earlier studies. It could be argued that, given a uniformly
distributed population of normal and dry eye subjects, the
most valid classification criteria would necessarily synchronize
normal means across different clinical measurements. The
composite methods used in this analysis have achieved that
end without specifically attempting to do so. Therefore, a
composite of clinical markers appears to be a valid surrogate
for disease severity.
