This is sort of a clinical picture from the baby point of view of what Dr. Chhibber was talking about. This is a funny slide, because I think it is backwards, but basically, this is on the Y-axis what we are looking at. This is death, this is percent BPD, and this is percent air leak, pneumothorax pneumo mediasteinum. And it compares groups of babies who have had four different kinds of treatment. Neither just surfactant, just antenatal steroids, and both. And what, if it is hard to see, these are the neither babies. They have the highest incidence of air leak , the highest incidence of BPD, and the highest incidence of mortality, and these are the both babies. So the ones who got both surfactant and steroids did the best in terms of both mortality. There was no mortality in this particular study, and a very significantly reduced incidence of air leak. They show a lesser incidence of BPD, it is not as dramatic as the other findings, but anything that decreases the incidence of BPD, we'll take, because it is a lousy disease to deal with.
