I read the interesting article by Jain et al. published in September–December 2020 issue of the Journal of the Practice of Cardiovascular Sciences. Using two-dimensional and M mode echocardiography, Jain et al. formulated the echocardiographic data of various routinely measured cardiovascular structures in Indian newborns up to 24 h after birth and derived Z-score graphs for those components. Apart from the few study limitations addressed by Jain et al., I presume that the following methodological limitation is also contributory. Ethnicity is an important determinant of generating nomograms of different pediatric echocardiographic measurements.,, India is a well-known and diverse multiethnic country that is the home to thousands of small ethnic and tribal groups. Regrettably, Jain et al. did not state the exact ethnic standard of the studied population. We realize that it is a major challenge to practically establish a research methodology on the neonatal echocardiographic Z-scores of the different cardiovascular structures related to a particular ethnicity in a multiethnic population such as India. Nevertheless, the effect of ethnic diversity must be taken into consideration during assessing the clinical applicability of the nomogram constructed by Jain et al.
