        The study was a randomized controlled trial to assess the effect of timing of umbilical cord&#xD;
        clamping on preterm neonatal outcome together The study was conducted in Kasr Al Ainy&#xD;
        maternity hospital, Cairo university hospitals which provides free obstetrics and gynecology&#xD;
        health services including antepartum, intraparturm, postpartum, and neonatal care for both&#xD;
        low risk and high-risk pregnant women A total of 80 pregnant women out of 120 meeting the&#xD;
        eligibility criteria were randomly pooled using computer-generated random numbers.&#xD;
  &#xD;
        The 80 randomly recruited ladies were randomly allocated using sealed envelopes to a group&#xD;
        from 4 equal groups (group A, B, C, and D) of 20 ladies each. Umbilical cord clamping was&#xD;
        performed immediately after birth (5 second) in group A, at 30 seconds in group B, at 60&#xD;
        seconds in group C, and at 90 seconds in group D.The trial was unblinded; where the&#xD;
        participants and researchers were aware of the group a participant belonged to.&#xD;
  &#xD;
        After the study protocol was granted the ethical approval from the research ethical committee&#xD;
        of Faculty of Nursing, Cairo University, Egypt, a written informed consent was obtained form&#xD;
        mothers of preterm neonate who met the inclusion criteria including the aim, procedure,&#xD;
        benefits, and nature of the study .The anonymity and confidentiality of information was&#xD;
        assured, and the mothers had the right to withdraw from the study at any time during the&#xD;
        study without any effect on the care provided to their preterm neonates.&#xD;
  &#xD;
        All study subjects were interviewed using a Structured interview questionnaire to obtain full&#xD;
        history to assess participants' demographic data such as age, residence, educational level&#xD;
        and occupation, past medical and surgical history, and obstetric history such as gravidity,&#xD;
        parity, and current pregnancy antenatal care.&#xD;
  &#xD;
        Immediately after birth, neonates in all groups are held 20 cm below the incision level.For&#xD;
        neonates in group A,umbilical cord was clamped and cut immediately after birth (5 second);&#xD;
        while, neonates in group B, umbilical cord were clamped and cut at 30 seconds. For neonates&#xD;
        in group C, umbilical cord was clamped and cut at 60 seconds. And finally, neonates in group&#xD;
        D, umbilical cord were clamped and cut at 90 seconds. After cord clamping, all neonates were&#xD;
        subject to routine immediate care.&#xD;
  &#xD;
        Neonatal data recorded included neonatal characteristic such as gestational age,birth weight&#xD;
        and gender.Neonatal condition was assessed and documented immediately after birth through&#xD;
        applying APGAR score of neonatal life, birth weight was measured immediately after delivery&#xD;
        through birth scale. Vital signs (respiration, pulse &amp; temperature) were measured birth.&#xD;
  &#xD;
        A pilot study was conducted on 10% of the study subjects. Eight preterm neonates who met the&#xD;
        inclusion criteria; the pilot study was carried out to test the clarity of the tool's&#xD;
        questions, and time needed to complete the tools. Additionally, to examine the applicability&#xD;
        of the study tool, and to identify any difficulties that may arise and need to be handled&#xD;
        before data collection. The pilot study revealed that the tools did not require modification.&#xD;
        The sample included in the pilot study was excluded from the main study sample.&#xD;
  &#xD;
        The collected data will be coded and statistically analyzed to obtain mean and standard&#xD;
        deviation for quantitative variables and frequencies (number of cases) and relative&#xD;
        frequencies (percentages) for categorical variables. Comparisons between groups will bedone&#xD;
        using analysis of variance (ANOVA) with multiple comparisons post hoc test in normally&#xD;
        distributed quantitative variables while non-parametric Kruskal-Wallis test and Mann-Whitney&#xD;
        test will be used for non-normally distributed quantitative variables . For comparing&#xD;
        categorical data, Chi square test will be performed.&#xD;
