Abstract
A critical examination is made of the results of a recently reported double blind trial comparing ritodrine and placebo. Interval estimates are more informative than P-values obtained from significance tests and the trial involving 49 patients was insensitive to differences which could be clinically important. Further evaluation of the effects of ritodrine in twin pregnancies is necessary to clarify the situation.This publication has 3 references indexed in Scilit:
