criteria was single cut of point method found by ROC curve. The second classification criteria was CPR value under <5th centile using Barcelona Calculator. The two methods of classifications criteria were applied on AGA and SGA groups independently. These two methods were compared and analysed for each study group. For statistical analysis T test and Chi square test were used as appropriate. Results: Over all, 481 pregnant women were eligible for the study, 170 in SGA group and 311 in AGA group. In the SGA group, Barcelona Calculator classification method was found better predictor over single cut off point method with Odds Ratio 5.2 and 3.01 respectively and Likelihood Ratio 19.3 and 10 p<0.0001, p 0.00151, respectively. In AGA group, CPR was not found predictor of mode of delivery in both methods. Conclusions: Classification criteria based on CPR value <5th centile to classify CPR as pathologic value, has been found a better predictor for mode of delivery in SGA fetuses group. In AGA fetuses, CPR was not found predictor with any of the methods of classification criteria.
