	abstract = {Objective: To compare the interpretation of agreement in the prediction of neonatal outcome variables, using the limits of agreement (LA) and the intraclass correlation coefficient (ICC). Study Design and Setting: Three obstetricians were asked to predict neonatal outcomes independently based on the evaluation of intrapartum cardiotocographic tracings. Interobserver agreement was assessed with the LA and the ICC, and the results obtained were interpreted by six clinicians and six statisticians on a scale that established agreement as very poor, poor, fair, good, or very good. Results: Interpretation of the LA results was less consensual than the ICC results, with proportions of agreement of 0.36 (95\% confidence interval [CI]: 0.28-0.44) vs. 0.63 (95\% CI: 0.54-0.73), respectively. LA results suggested a fair to good agreement among obstetricians, whereas interpretation of ICC results suggested a poor to fair agreement. LA results were more plausible with reality, suggesting that obstetricians predicted neonatal outcomes better than randomly generated values, whereas it was not always the case with the ICC. Conclusions: LA and ICC can provide inconsistent results in agreement studies. Accordingly, in the absence of better strategies to assess agreement, both should be used for this purpose, but their results need to be interpreted with caution keeping their respective limitations in mind. {\textcopyright} 2011 Elsevier Inc.

	abstract = {Objective To evaluate the impact of access to computerised cardiotocograph (CTG) analysis on reproducibility and accuracy of clinicians{\textquoteright} predictions of umbilical artery blood pH (UAB pH) and 5-minute Apgar score. Design Prospective evaluation of pre-recorded cases. Setting A tertiary-care university hospital. Population From databases of intrapartum CTGs acquired in singleton term pregnancies, 204 tracings with low signal loss and short time interval to delivery were consecutively selected. Methods Tracings were randomly assigned to computer analysis by the Omniview-SisPorto 3.5                        {\textregistered} system (study group n = 104) or to no analysis (control group n = 100). Three experienced clinicians evaluated all tracing printouts independently and were asked to predict the newborns{\textquoteright} UAB pH and 5-minute Apgar scores from them. Main outcome measures Interobserver agreement (measured by the intraclass correlation coefficient [ICC]) and accuracy in prediction of neonatal outcomes with 95\% CI. Results Agreement on prediction of UAB pH was significantly higher in the study group (ICC = 0.70; 95\% CI 0.61-0.77) than in the control group (ICC = 0.43; 95\% CI 0.21-0.60), and a trend towards better agreement was also seen in estimation of 5-minute Apgar scores (ICC = 0.55; 95\% CI 0.38-0.68 versus ICC = 0.43; 95\% CI 0.25-0.57). Observers predicted UAB pH values correctly within a 0.10 margin in 70\% of cases in the study group (95\% CI 0.61-0.79) versus 46\% in the control group (95\% CI 0.35-0.56). They predicted 5-minute Apgar scores within a margin of one in 81\% of cases in the study group (95\% CI 0.73-0.88) and in 70\% of cases in the control group (95\% CI 0.61-0.79). Conclusions Prediction of UAB pH is more reproducible and accurate when clinicians have access to computerised analysis of CTGs. {\textcopyright} RCOG 2010 BJOG An International Journal of Obstetrics and Gynaecology.
