Statistical methods / analysis
Data will statistically described in terms of range, mean+/- standard deviation (+/-SD), frequencies (number of cases and percentages when appropriate. Comparisons of quantitative variables between the study groups was done using one way analysis variance (ANOVA) test with postoc multiple 2-group comparisons. Within group comparisons between pre and post treatment values will be done using paired t test. For comparing categorical data, Chi square test will performed. Exact test will be used instead when the expected . the power of significance will considered if P value at or less than 0.05 , level of attrition should not exceed 10-15%

Summary
Brief summary
This is a comparative study that will performed in the period from July 2016 to July 2017. In total 300 patients will be recruited from the Obstetric department in Minia University Hospitals with preterm labor symptoms between 28 and 37 weeks gestation. Participants will be randomised into one of three groups: Group A: 100 patients will receive oral nifedipine (epilate capsules) Epico. Group b: 100 patients will receive progesterone vaginal suppository (prontogest 400 ) IBSA. Group C: 100 patients will receive oral ritodrine (yutopar) Pharco pharmaceuticals. Patients will be followed up weekly in the obstetric outpatient clinic until delivery to detect the date and mode of delivery and the fetal outcome. Repeated episodes of preterm labor that might occur will be recorded and treated with the same treatment group(1) will receive CCB (calcium channel blockers) nifedipine oral epilate capsule 20 mg/8 hours till 37 weeks gestation or till delivery whichever occurs first
group two will receive progesterone pessaries containing 400 mg of natural progesterone per pessary one pessary per vaginum at bed time until 37 weeks or till delivery whichever occurs first, regular follow up in the OPD and return of empty packet is strategies will be used to monitor adherence. Gestational age at delivery, proportion of neonates that not exhibit any medical condition at time of discharge (within 4 days after labour) and proportion of neonates that will need NICU admission will be recorded
