Predictive value of, and observer variability in, several ways of reporting antepartum cardiotocographs

Abstract

Summary. Each of three scoring systems, and oscillatory frequency, had significantly poorer correlation with fetal outcome than reporting the cardiotocograph (CTG) as either ‘reactive’ or ‘non‐reactive’. There was no significant difference in the intra‐ and inter‐observer variability when the CTG was reported in this way.
