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.
