ABSTRACT

If stature follows a Gaussian distribution, then the height between the 2 SD will constitute normal height (Fig. 1A). The individuals below 2 SD (or 2.25, 2.5, or 3 SD, all are arbitrary points) will be considered having short stature (Vol. 2; Chap. 1). if the reasons of the short stature in these children are unknown or the investigation does not reveal any pathology, these children are then labeled as ‘‘normal short child’’ (Fig. 1A).
