NCT03440281

Brief Summary

Study included all pregnant women admitted with threatened preterm labor during the study period. All participants underwent estimation of maternal serum homocysteine level and assessment of uterine artery Doppler indices.

Outcome Measures

Primary Outcomes (1)

  • The accuracy of serum homocysteine levels and uterine artery pulsatility indices (UtA-PI ) for prediction of preterm labor

    Sensitivity (%), specificity (%), positive predictive value (%), negative predictive value (%), positive likelihood ratio (number), negative likelihood ratio (number), accuracy (%) of serum homocysteine and UtA-PI for prediction of preterm labor

    Single measurement at the end of the study ( around 37 gestational weeks)

Secondary Outcomes (2)

  • Gestational age at delivery

    Single measurement at the end of the study ( around 37 gestational weeks)

  • Demographic and clinical characteristics of the study groups

    Single measurement on the day one of hospital admission between 28-35 gestational weeks

Study Arms (2)

Preterm group

included pregnant females delivered prior to completed 37 weeks of gestation. All participants underwent assessment of uterine artery Doppler indices and maternal serum homocysteine estimation

Diagnostic Test: Uterine artery dopplerDiagnostic Test: Maternal serum homocysteine estimation

Term group

Included pregnant females delivered after completed 37 weeks of gestation. All participants underwent assessment of uterine artery Doppler indices and maternal serum homocysteine estimation

Diagnostic Test: Uterine artery dopplerDiagnostic Test: Maternal serum homocysteine estimation
