Research implications
Although, in the past years, the field’s focus has been to answer which
chart we should use, one alternative might be to identify cutoffs for
each standard in which the perinatal morbidity increases, which might be
not necessarily the 3rd or the 10thpercentile. Such perinatal risk-based cutoffs can be an opportunity to
provide personalized care (52,70). This strategy might enhance the
clinical applicability and use of the two standards while adapting to
local scenarios. Environmental constraints are also a well-known factor
influencing fetal growth, and usually, growth percentiles are not
controlled adequately. Therefore, in addition to the argument about
which chart should be used, the debate should move on to integrate
functional parameters that enhance the fundamental objective in
antenatal care, which is to assess placental function rather than fetal
size.
