Any possible associations between the absolute percentage error of fetal weight estimations and the maternal and fetal data were examined.</p><p><strong>RESULTS:</strong> In 135 of the 371 women (36%), the absolute percentage error was greater than 10%. The mean absolute percentage error was 8.7±7.5%. The mean absolute percentage errors were 4.1±2.7% and 16.8±6.4% in the accurate and inaccurate estimation groups, respectively.<br />The rate of women examined during labor was significantly higher in the inaccurate estimation group compared to the accurate estimation group. There were no significant differences in age, body-mass-index, gestational age at delivery, estimated-fetal-weight, actual birth weight, days from the last ultrasound examination to delivery, small for gestational age rate, placenta localization or fetal presentation between the two groups. <br />Examination during labor (β=0.224) was the most important factor for the prediction of the absolute percentage error, followed by gestational age at delivery (β=–0.198), presence of (β=–0.158), and body-mass-index (β=0.142).</p><p><strong>CONCLUSION:</strong> In 36% of our study population, the absolute percentage error was &gt;10%. Examination during labor was the most important factor for the prediction of the absolute percentage error, followed by gestational age at delivery, presence of small for gestational age, and body-mass-index.</p> ER -
