Erratum to: Clomiphene Citrate co-treatment with low dose urinary FSH versus urinary FSH for clomiphene resistant PCOS: randomized controlled trial

Abstract

It is clear from the table that the provided values resulted in almost the same statistical differences and thereby same conclusion. Dr. Papathanasiou has admitted that the statistical significance observed in our study was not changed after making the amendments. Meanwhile, he expressed his concern that the effect size statistics may have changed. Our research question was whether clomiphene citrate plus gonadotropins was as equal as gonadotropins alone or not, in terms of ovulation rate. The questions about the effect size and the number needed to treat may be important points when making inference and recommendations for the general population. In our study we acknowledged the need for larger trial or a metaanalysis of small randomized trials. Either of these, may be the optimum platform to calculate statistical measures as effect size and number needed to treat.As regards predictors of ovulation, we attempted to underline the relative importance of features of CC-resistant PCOS as predictors of treatment outcome. Although multivariate analysis was the better statistical tool for this purpose , yet, and as suggested by our statistician, the ROC curve has been used in similar situations [1,2].Dr. Papathanasiou has mentioned contradiction between the confidence interval (0.51-0.77) and the p value (0.05), the reported P value of ( 0.05) resulted from summing up of The online version of the original article can be found at http://dx
