Study objectives | The aim of this trial is to compare the effect of immediate or delayed delivery for premature fetuses with good evidence of failure to thrive in utero. Cases will be stratified by gestational age and the degree of abnormality of test results. The sole entry criterion will be obstetrician uncertainty about the best management. The primary outcome measure will be Development Quotient at two years of age, with deaths included and scored as zero. The analysis will be stratified by gestation and the degree of test abnormality. Please note that, as of 14/02/2007, the target number of participants has been updated from 548 to 510 (233 UK; 277 non-UK). |
