Hypothesis
The study aims to evaluate inter- and intra-observer variability in sonographic measurements of the umbilical cord and its vessels in low-risk pregnancies.
Conclusion
Inter- and intra-observer variability in the measurements of the umbilical cord and its vessels was small, indicating good reliability and agreement.
Supporting Evidence
- The study included 221 low-risk pregnant women.
- Measurements were taken by two different observers to assess variability.
- Statistical analysis showed good reliability with high correlation coefficients.
Takeaway
Doctors can measure the umbilical cord and its vessels during pregnancy, and different doctors will get similar results, which is good for checking on babies.
Methodology
A prospective cross-sectional study was performed with 221 pregnant women, measuring the umbilical cord and vessel diameters by two different observers to assess variability.
Limitations
Different techniques were used for measuring at various gestational ages, which may affect results.
