Reply to Comment on Sonographic Portal Vein Biometry among Apparently Healthy Children in Northeastern Nigeria

Dr. Mahmood Dhahir Al-Mendalawi is right about his assertion on our research work published in January–March 2020 issue of the Journal of Medical Ultrasound,[1] which was aimed at determining the mean portal vein diameter, based on age, gender, and anthropometric indices among a cohort of apparently healthy Nigerian children aged 0–18 years. Previous studies both locally and internationally using a similar method reported similar findings,[2-6] as shown in Table 1.
