title: [Limitations and applicability of predicted values of the main spirometric parameters in a childhood population].
abstract: Different ethnic origins have considerable influence on the various biologic parameters. In respiratory physiopathology variations become even more pronounced especially when we consider the growth, the used methodology and the cooperation of the child. In order to obtain predicted values of the main spirometric parameters in the sicilian pediatric population, we studies 196 boys, whose ages ranged from 10 to 13 years. The short age range and the high number of boys examined, has allow us a more accurate statistical evaluation. The Fenyves and Gut pneumotacograph (Basel) has been used to determine the flow-volume curves. All of the obtained data have undergone statistical analysis with the multiple correlation method. With this method we derived our predicted values, which were significantly different from the results of other Authors. It than becomes necessary that every respiratory physiopathological center derives its own predicted values, due to the variability linked to the kind of spirometer, the way the test is used and the ethnic group studied.
