Our study had the function of determining whether the intergrowth-21 ultrasound formula is superior in predicting fetal growth restriction than hadlock-4 in pregnant women treated in the gynecology and obstetrics service of the José Alfredo Mendoza Olavarria Regional Hospital. Materials and methods: An observational, analytical, cross-sectional study was carried out on diagnostic tests of pregnant women treated at the José Alfredo Mendoza Olavarria Regional Hospital during May 2022 to August 2023. Pregnant women who had undergone ultrasound with both were recorded in the medical records. ultrasound formulas, to distinguish which formula has the greatest prediction for fetal growth restriction. Results: This study included a total of 162 pregnant women who received care in an outpatient clinic or emergency clinic of the gynecology and obstetrics service of the José Alfredo Mendoza Olavarria Regional Hospital, where it was observed that hadlock-4 had a sensitivity of 98.9%, a specificity of 81.7%, a PPV of 87.4% and a NPV of 98.3%, while intergrowth-21 had a specificity of 84.6%, a specificity of 97.2%, a PPV of 97.5% and a NPV of 83.1%. After comparing both results, we observed that the likelihood ratio The highest was obtained by intergrowth-21 with 30.038, likewise the lowest negative likelihood ratio was obtained by hadlock-4 with 0.013, which indicates that hadlock-4 has a high diagnostic precision. Conclusions: The hadlock-4 ultrasound formula was superior in predicting IUGR than Intergrowth-21 in pregnant women attended at the José Alfredo Mendoza Olavarría II-2 Regional Hospital.
