    We thank Ovali et al for their interest in our paper. They emphasise that BPD results from a multifactorial process and has wide variation in severity. We agree that basing the prediction of BPD solely on ventilatory requirement at one week of age would not identify all cases of BPD, as demonstrated by the low sensitivity of 67% demonstrated in our study.[1] The high sensitivity of ventilation at one week of age in predicting the development of BPD (99%), however, means that it could facilitate counselling of parents and act as a screening tool to identify candidates for future trials of therapeutic interventions to prevent BPD.

    To the editor;
    We have read the study of Hunt et al. describing the prediction of bronchopulmonary dysplasia (BPD) development at 1 week of age. (1). As it is very well known, BPD is a multifactorial disease with different clinical forms such as mild, moderate and severe. Early prediction of the disease is a clinically significant issue, such that early preventive measures may be taken, especially in cases with high risk. In our opinion, basing the prediction of BPD only on the ventilation requirement at 1 week of age is not appropriate. Respiratory distress syndrome and mechanical ventilation are important factors in the development of BPD but mechanical ventilation need is not sufficent enough for prediction in a disease with many risk factors. We had developed a simple clinical scoring system for the prediction of BPD, which takes into account the birthweight, gestational age, gender, hemodynamically signifiicant patent ductus arteriosus (HsPDA), respiratory distress syndrome, hypotension and intraventricular hemorrhage, at 72 hours of postnatal age (2). A score of less than 4 was considered as low, 4-6 as low intermediate, 7-9 as high intermediate and a score of above 9 was considered as high risk, in order to optimize the predictive values of lowest and highest categories. Among these parameters, HsPDA was the most significant one. The receiver operator curves (ROC) was 0.930, the negative predictive value of a score less than 4 were 95,9 whereas a positive pre...
